I built a mouse from scratch with 3D printing and Arduino 

I love the attention to repairability in this design.. nice work !!

Photogrammetry often uses the background to figure out what angle you're taking the picture from, so putting it on a turntable without extreme measures to 100% remove all background is exactly the wrong approach.

Btw if you use a subdivision based workflow in blender, you can export the unsubdivided base mesh as a quad obj. You can import this into fusion 360, convert to t-spline in the form mode. When you close the form mode, you are left with a shape very close to the original subdivided model. I mention it as I find SubD modelling in Blender so much faster and easier than messing around with organic shapes in Fusion.

Nice. I can never seem to find the right mouse and have thought about making my own. Thanks for sharing your process!

Super cool! Love the photogrammetry to get a perfect fit for your hand. Your end shape actually reminds me exactly of the Mionix Naos, which is the most comfortable mouse I've ever owned. Great project!

Thanks for taking us along for the journey! Love the project!

ty for thissss I've been working on my own from scratch and it's been difficult to plan this from the ground up, from sensors, ICs, and wrapping it up into a PCB design. It's been hard to find others documenting the journey, especially at the level I'm trying to do it.

Really nice take on custom mouse project, kudos to you

double index & middle buttons is something i now want on every mouse

love your videos. you make it seem/sound so easy, like, "oh, I just did that." it's very inspiring

Not easy picking up PCB design. Great stuff Ben!

Great project involving many different disciplines, well done !

I picked up a Logi G305 Lightspeed a few years back and was surprised at how modular and repairable it was. After a few years when a click (left, I think?) inevitably died, I just... opened it up and desoldered out the switch to swap for one from a random other junk mouse I had. Never really thought it'd work but it's been great, and I've been curious about 3D printing a custom shell to put its guts into for even better modularity, but now I'm curious about just making one from scratch! What a great video!

Really cool! I've always wanted to try making a DIY mouse but wasn't sure where to get the optical sensor, definitely going to keep this in mind!

"I decided that its time to quit putting off the inevitable and finally LEARN PCB DESIGN!" , "Finally decided to learn Python", "Ok its time to learn..." its like a pattern in every video,... Love how you like to challenge yourself and keep learning. applause

This is my first time watching your channel and I loved this video -- great job! Subscribed

OH MY PKCELL!!!!!!!!!!

This is incredibly impressive, awesome job!

I love this. Keep making videos. They are greatly appreciated

Hell yeah, I love it! Wanted to atempt it myself but didn't know whete to start from

Awesome build, really well done!

I would definitely buy one of these (I have no idea about programming/assembling it), but it looks so nice and I really love the idea of keyboard switches on a mouse. Great job.🎉

i love it! i have always wondered about a mice with keyboard switches finally someone made it!

awesome stuff, been looking to do something like this for a while seeing at how big custom keyboards are and how nobody is really making custom mice as far as i know

Liked & subscribed. Great stuff all around in this video.

Very nice! Thank you for sharing!

Dude, amazing work.

Lovely design. I hope to see a more polished V2 some day

Good job! My first thought was that instead of a rotary encoder, you could use a BLDC motor - and even do custom dents into whatever mode you want to use! Not sure if it would be a better scroll wheel, but it WOULD be super neat to see you attempt it hahaha Either way, very cool project! Keep up the great work!

Incredible design

Very well done, thanks for sharing with us

Nice project! love it

Really cool build Ben! I always appreciate it when people include the bumps on the road along the way to victory :). Reminds me that we are all human and it's normal to fail some times. That being said I'd say the result compared to the original idea is bang on. Even the build quality and easthetic's are nice. Don't ask me why but I'm addicted to the thumb button cluster on the razer naga hex v1. I've been keeping it alive for almost 10 years. I'm on my 3rd set of buttons 😂. When it eventually dies I'll most likely build something very simmilar to you. Something i haven't seen yet is a smooth finnish on a 3d printed mouse. I haven't tried it yet but if you print in ABS with a small layer height and smooth it with acetone I'm pretty sure you can achieve something very smooth and comfortable. Thanks for reading my essay. Cheers!

This is awesome. I've been using a Steelseries Rival 500 for idk how long now and its not manufactured anymore. i had to fix it countless times. swap out switches, replacing the cable, glueing broken pieces back together etc since no other mouse does it for me like this one does. it fits perfectly in my hand and has exactly as many buttons as i need. But i never thought about making my own mouse which would fix my issues. im gonna try to do this :D

I LOOOOOVE that scroll wheel on the side. The size, placement and able to use it while still using mouth mouse buttons. I would kill for some low profile mx switches as my mouse buttons.

Using those optical/hall sensor switches would've been insane also, so you could program them as axis buttons too for driving games throttle/braking etc!

Very cool and inspirational!

Hello Ben. I really like your project,but i have a question. It could be possible to integrate (buying from Ali MagSpeed scroll wheel) the induction MagSpeed scroll wheel from logitech MX3 in to this mice???? I'm super interested abut this,because after i got the MagSpeed wheel under my hands, I won't never again ride ordinary scroll wheels encoder again. Thanks.

It's amazing. I now have a thing that I can do and reference you when I have time and money to afford it. Great project to do on vacation.

so cool! I love this mouse!

YT randomly recommended this and I'm so glad it did. I love my Logitech M575 trackball, but the main switches have a tendency to fail in a year, and for gaming the polling rate and latency sucks. Once in a rare while I'll get it in my head that I'll learn what I need to build my own and will spend some time looking up people's DIY mouse projects for inspiration. This is maybe the best example I've seen yet that gives me hope that one day my dream of the perfect M575 alternative will exist.

Love the project and I've been looking into building my own mouse for a bit now but I'd say that repairing a mouse is far easier, especially the scroll wheel. I had problems on my Razer Naga Chroma's scroll wheel and for anyone interested all I had to do was unsticking the plastic adhesives that cover the screws (gently, being careful not to break them to reuse them), unscrew the bottom, unscrew the mouse wheel rotary sensor (just another screw) and opening it. Inside there are some small metal legs that push against another metal part. In most cases to fix the sensor it's enough to bend the metal legs a little bit outwards using some tweezers, to make sure that they make contact with the other part of the sensor. After that put everything back together and that should be it! It's that easy and doesn't cost you a penny. If you have some at home I'd suggest putting a tiny bit of lube in it, such as wd40, it will help the contacts last longer without interfering with the functionality of the sensor. For the buttons it's a tiny bit more complicated, but nothing that you wouldn't have to do if you consider building your custom mouse: soldering! You just have to spend a few cents for another mouse switch (or rescue it from another broken mouse), open up your mouse, locate the switch that isn't working. Then you just have to desolder the old switch and solder in the new one. To desolder it, if you don't have the tools to do it don't worry: you can improvise and try to do the job using just the soldering iron. You just have to hold the tip of the iron on one of the pins that you have to desolder until the solder gets melted, then you try to move one part of the switch out (doesn't matter if it doesn't completely come off, don't rush it). Once done do the same for the other pin of the switch. You continue to repeat this bit by bit until the switch eventually comes off. Then you solder in the new one and another mouse has been saved from the trash! ps: just to make it clear, no hating here! Just a guy, whose primary language isn't english, that is trying to share some knowledge with people that may need it or just be interested :)

Love the video !

Oh man I don't what your background is but you are kind of the perfect mix of artist and engineer, truly inspiring work there

I'm a big fan of the thumb scrollwheel idea

Awesome project.

I definitely want to make something like this sometime, it seems like it would be super useful for me.

Another awesome video!

Really good!!

This was so cool!

Those keys are looking real good 🙆🏻‍♂️

Super cool project dude! How is the latency of button presses on the wired version? Do you have some way to test it? Maybe you could have some program running on your computer that would "respond" to the mouse (sending some command back) and then test the roundtrip time?

I love the idea of mechanical switches on a mouse. Nice work.

Good video and well explained. Having big hands and playing FPS can get painful. I have been working on one myself that has a Cortex-M4 at its heart, dual sensors, as well as a different suite of buttons. In shaping the body we took almost exactly the same steps, I just did more smoothing in blender. Also some of those rotary encoders have COM on the side pin.

Awesome! The only thing I'd change is to either sand the surface or use acetone smoothing on it. Although, you probably appreciate the extra grippiness of the unsmoothed print.

Super cool!

Man! You are God send for my Arthritis! Thank you very much!

Fellow big hand here, yeah i was thinking of just going for a case mod that way i can still keep the pros of the G502 but still be able to use the thing. Was actually watching this video as I want to make a wireless mouse but in the shape of a pen, so the sensor is the pen tip, as a means for me to learn art without investing into a graphics tablet as I could also make a modular keyboard setup for all the hotkeys and such to use in whatever app i will use! Great vid

Very cool!

Nice design

Thank you! Finally someone else who understands the beauty of having extra left and right clicks!!! My favourite mouse of all time still is the Roccat Tyon with 16 buttons spread out evenly over all fingers with 32 functions using the onboard shift key (non of the thumb keypad BS!). Unfortunately that mouse was too niche and was pulled from their lineup after a short production.

I had the same dream some 3 years ago. My problem then was sourcing the sensor. Maybe I'll look into it again now. Thanks!

man ! straight out of some sci-fi movie ! i would rlly have a gaming mouse with such asthetics .

thats awsome!

PLEASE make a full Tutorial series on how to program an Arduino / How you learnt how to program it, how you learnt to do all the wiring, 3D Designing etc. Basically a full "DIY Course" would be awesome (I REALLY want to get into that kind of programming but don't know where/how to start..)

Superior content, sir!

Great job:)

I need it 💓... thank you I loved the video

i love the idea of putting extra buttons for the index and middle fingers, instead of doing like the razer trinity where you have to press everything with your thumb

One more GOOD CONTENT, Ben!

question, how close did you have to get the sensor to the table surface the mouse is on to work optimally?

Cool build! I was looking at doing something like this but I'm stuck in my current projects code as I know very little about Arduino code. Might be able to get round to it in like a year lmao

Awesome!

good job! just an idea would it be nicer to use transparent filament maybe since the inside components (chip and wheel) looks cool

If you have a magnifying rig like a head mounted loupe, it's actually not that hard to solder surface mount stuff as long as the pins are visible and you have a small enough tip to work with. That rules out BGA and QFN packages, but you still can do a lot without them. It does eliminate the ESP32 mini module variants, though.

I will definitely be making this

This is really cool.

this is really cool, nice job. I've been a logitech trackball user for years due to my needs and the quality of the switches has gone downhill in all of their mice. one used to last me years and I replaced the last few withing a year because of faulty clicking. finally had to swap out the switches with some kailh blue 2.0 -that fixed that but the rubberized plastic and micro usb are def not made to last.....

So great. It would be neat if you released a standard ‘core’ that people could build then just add their own 3d printed grip on top. (Opposed to having to redesign the entire shell)

Wow finally somebody promoting the PROMICRO, my favourite 😍

nice project, i allways used the logitech mx series. now i have the mx master 3S and i love it. mainly because of the thumb scroll wheel.

beautiful mouse

nice mouse! nice jacket too!

Really cool project - wouldn’t mind making one and I can think of a few other uses for some of the tools. Obviously a bit of a late suggestion, but I wonder if you could get the Arduino version of the code to work with a nice!nano? It’s sold as a drop in replacement for the Pro Micro, and it seems like folks have gotten it working with the PMW3360 trackball.

That's really really cool I should make my own mouse though i might stick with the flappy paddle mouse clicks

Would you say there's any latency with button presses on the wireless version?

very cool!

Sweet i want to make a classic style gaming mouse with a trackball on the bottom

Great execution! I've been wanting to make something like this for a while. I'm thinking of a vertical/canted mouse with a small joystick by the thumb, and extra buttons. How heavy did the wired one end up?

Man I am over here trying to figure out how to fix my g903 because its the only "gaming mouse" that comfortably fits my had. I use palm grip. I cant even figure out how to make 3d printed base and shell to lighten her up lol. This guys over here designing his whole mouse himself. Great job man!

That's joyful to watch

awesome . i wished the mouse makers make bigger ergonomic mouses like yours

i love the vid bc i searched for that for yearsbut didnt found any (with the electronics part). i have on question tho, can you build a pcb and then solder a sensor directly on the board?

What size heated inserts and therefore bolts did you use? I'm thinking of building this thing myself, it looks amazing!

That is awesome! Your scroll wheel grabbed my attention. It looks like it has to make your UX better with this main buttons. In general mouse looks great, but I was left upset when you didn't reveal the weight :( Maybe it was too important to me. I just love how some people get creative out of their annoyence. These products are the best! What is even more cool - that you do it for yourself mostly BY yourself :D Thanks for the video!

Really cool project! How much did the final project end up weighing? Definitely seems on the heavier side

Bro That's Cool I recommend you to make your own company you are genius.

now time for a keyboard from scratch

Good afternoon. Tell me, is it possible to make an analogue of adaptive triggers and vibration like the dualsense for a mouse?
