7 Segment Counter v2.0 Tutorial, 3D Printed, STL Files Link 

New Version v3.0 video here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-LMwjKzrQjHg.html

A potential feature idea is to have carryover output/input so you could chain them.

That has to be the best project ive seen for a long time - bravo. Tempted to make a clock using steppers with it

Finally a handheld way to count to ten

Compliant springs in place of the bands and a way to link multiple together would be fantastic upgrades. Great project, thanks for sharing! :)

I printed this for my numbers-obsessed kid, and he loves it - he was very excited to help me put it together! And thanks for adding the printed screws, saved me a trip to the hardware store.

This is a super impressive project considering that the only non-3d printed things needed are rubber bands and a couple screws. You could probably even design it to be held together without screws. Super impressive. Well done.

What a beautiful design! Assembly so satisfying that I am going to print this, assemble it and then take it apart and give the parts as a present. Your video serves as the assembly guide.

If this is not genius, nothing is.

I love this design a lot! A lot of these highly complex models are insanely difficult to assemble but this is poka yoke heaven! Product design mastermind.

Wow! I love this, thank you for making the files available for all of us. I immediately thought of using it to make a counter for our sports match, which is currently made out of paper and no one wants to go there and turn the number after a goal. With this tactile feedback, I wouldn't be afraid of it. xD So I basically need to connect two double counters together!

Thank you for sharing this and making the files available. Very well designed and explained. Great for helping my grandchildren to count!

You are an amazing person for giving this model out for free. I wish you 20 million subscribers and all the wealth in the world. Have a nice day!

I think the design of this product is very beautiful, this is how products should be made. Pragmatic and reparable

Pretty impressive! Purely mechanical projects are so satisfying.

i am happy I landed on the good side on RU-vid. Subscribed. What you have given me is ...food for thought. I may or may not attempt this...but there are many things I learnt from this video. Thanks a bunch!

This is absolutely brilliant. The design must have taken ages!

Thank you a lot. This is going to be my 1st project of 3D print as this is so greatly designed and step-by-step guide.😊

I am not sure why anyone would want something like this, but it is very interesting.

WOW! Why did the RU-vid Gods take so long to show me your channel!?!? I'm printing this and subscribing. Keep these free designs and great videos coming!!!

Fascinating! You have a very pleasant and calm voice, clear instructions and the project seems "doable", it really tickles me to power up my 3d printer right away! ☺ Thanx very much, you got a new subscriber!!!

Im printing 2 of the 2 segment versions for a competition im holding. THANK YOU!

I really love this thing, great design! I might have an area of improvement: The „locking spring“ (inner part of the spring) doesn’t have enough force to lock number one into place (after some use). I guess it needs the most force out of all the numbers when counting form zero to one. It worked fine at first but after some use it won’t count from zero to one. I‘m probably going to squeeze some foam behind that spring to increase the force. For a design improvement: Maybe „support“ the spring by making the cam flat or even a little bit concave at the number one position. Of course stiffening the spring somehow would work too. It could also be that I‘m missing something.

Count down and / or connecting multiple segments would take this over the top. Amazing work keep it up. +1 for subscriber count!

This is absolutely beautiful - design/theory and execution. Awesome. A mod to allow for servo control (to make a clock) would be great.

F' ING BRILLIANT !! How satisfying is that! Thank you, this is a fun project. Mine is half printed so far.

This is a very cool project! Thanks for sharing - I admire the dedication to making something like this and taking the time to explain the operation.

I have absolutely no idea what I’d use this for but I want one.

Awesome job. It is a just mechanical mesmerising mechanism to look at. I ❤ it. As a mechanical engineer who like to play with his 3D printer, I clearly now what my next print will be.

Awesome project. For the inner parts not to be seen, you can use a constant white background as a zero, and hide the relevant segments when counting, using the same case's color.

Such a nice video. Impressive design and a very good and full detailed explanation. Thank you!

I can definitely tell you’re a This Old Tony fan, awesome project!

Fantastic work here!

Amazing design and great build video. Thank you for sharing with us.

This is cool as hell. 7 segment displays will always have a special place in my heart, because I had to lead and carry a group project designing a FPGA circuit for a countdown timer driving one of these. Translating that into something so physical, so mechanical, is awesome. Great design.

What a great job!!! The only thing I'd change is replace the 4 dome type screws with flat heads to make the whole stack back flat.

This is one of the coolest things I’ve seen! What a cool and accessible project for 3D printing.

Thanks for making this really cool design free. You are a real one for that.

Nice design! Clever cam and gear arrangement. I'll test this at my grandson's hockey games and we'll see how it hold up.

Beautiful project, congratulations, I'd love to have a 3D Printer to try it, really good stuff, it is wonderful what it is possible to do nowadays with one of those machines, thanks for sharing!

Bless you for making this available.

wow, just appreciate all the work that went into it behind the scene. Only thing I would change is to remove the visible slot, although this might make the device slightly wider

This is SO great. Beautiful design. How about adding another timing gear that can protrude sideways and power a carry in the neighbouring unit. So we can have 2 or 3 chained for larger numbers. Just brilliant bravo!

That's pretty cool, could use something like that when I am loading my dump trailer so I don't overload it with buckets from the tractor.

You've earned yourself a new sub JUST based on this video! Can't wait to see what else you've done and will do!!

Ain't gonna lie, this is pretty cool. Subscribed.

Bravo, it is good work and very intelligent.

Incredible engineering. Thank you for sharing.

I like how the 6’s have the tops

Very nice design with a great end result!

I really like this! Great job

This is SO. Friggin. COOL!!

Poka Yoke: If you offset the key in the shaft out of the center, each with a different amount, you'll prevent wrong assembly of the cam wheels - 6:28

Super Nice design! And clear explanation. As a remark I would like to mention that having it fully printable would be a big plus (with compliant springs). Rubber bands do not last that long and need to be sourced. Any ways great project!

Fantastic build and looks like a works an absolute treat! Have to say I am getting some serious This Old Tony vibes from your content production :D

You did really well there! The most I like it's the inners, because it looks like it could be driven by a motor. And maybe you didn't think of this, but if you can stack these in sync, (and in parallel) these could be used to replace all the electronic ones seen on almost every shop, so that not electric power would be needed to run these. All the best!

its impressive how you get soo much, with soo few parts, and interesting combo of simple complexity. my suggestions are.... 1. silicone bands, since rubber bands degrade pretty quickly. 2. the ability to select a number, not just cycle through till you reach the one you need. 3. use M3, M4, M5, screws, not wood screws, as they are the standard for 3d printing, and lots of other things, and would be more common for people to already have, or find. 4. version with and internal button, or is otherwise hidden, instead of sticking out the top, so you can make a nice neat looking clock with it.

Nice design. Now it could use a carryover to combine multiple modules while retaining only one push button.

Once again a video makes me wish i had a person that could 3D print things for me. Of course i would pay the material costs and some for their time. Its a shame you dont sell these.

Level 1000 version. Print in place completely assembled and with 4 digits

This deserves a 👏 and a subscription... This is absolutely top notch and great audio quality which I appreciate. Thx

Totally outstanding content. And this is a very impressive design. Thank you for all the effort you put into this video. It was well done.

I just want to click it! Thank you! Imagine one where the numbers count in reverse for a countdown!

Slick design, easy sub, look forward to everything you create

Very well done, I could have used these years ago for outdoor sports score keeping.

This is pretty slick. Though on something I designed that had rubber band then spring approaches someone redesigned it to use magnets (reversed poles) to work as springs which was a good idea in the compact space + for a longer lifespan.

Amazing! I guess you would need some kind of pivoting mechanism instead of the current sliding mechanism to get rid of / hide the tracks for the segments... Otherwise I would recommend printing it in black to hide the tracks, which add visual noise to the numbers. If possible, chamfering the outlines of the cutouts would also help reduce the shadow cast on unused/empty segments. Incredible design, execution and video!

Really cool idea! I'll have to try making one one day!

Really cool, my grandson will love them.

That is so cool. A smaller version with ~3 digits could be very useful.

Awesome mechanism! Bravo, subbed

Awesome work! My first thought goes to how you could make this display electrically driven (which would probably also need a zero position feedback). You could then use multiple segments for making a clock, or a multi-segment counter etc. That would be even more awesome!

*_Absolutely fabulous!_*

This is brilliant. Now to figure out how to attach this to a chip and a motor for a clock

Fantastic creation, very clever and smooth, thanks!

You could try to hook a solenoid pushers up to the step button so an arduino can run it as a clock and try to read the watt hour of the system to see how efficient of a system it would be compared to a led clock

Very nice 👍🏻 Thanks for sharing 👍🏼

Wow! nice bit of engineering.

As a v3 suggestion: Make it so the "rails" aren't visible when the white digit parts are away. You could achieve this by actually moving the rails away and making the white parts with little "arms" to connect with the black parts further away, but maybe this'd make the entire thing a bit bigger.

Bro you shouldve made this a paid for item on printables, its crazy high effort!!

Quick tip. You seem to have a number of parts that can be assembled in multiple orientations, but only one orientation is correct. You can use asymmetrical holes/shafts/pins/etc. so that there's only one possible way to assemble, and no instructions are needed. For instance, the cams. If it's a D shaped profile they're sliding onto, then they'll always be clocked correctly when assembled.

Very good design. Congrats!

Outstanding somehow useless piece of engineering. However I love, inspiring. Designing it in a steampunk spirit would have been the grail. Thanks for leaving this to the many of us who will get inspiration from your project.

Wow, amazing! 👍 Now do whole watch run by electric plz. 🤓😉🙏 Oh you already did it! 😮😃👍

Great design and presentation!

Great Build! Subscribed. Looking forward to your future projects

Very cool, subscribed

Great design and great video explaining it!

Beautifully done!

Interesting project, my first thoughts were a clock or multi digit counter, then I saw you did a clock video using it. Subbed, curious to see what else you come up with.

Amazing work!

Wow! Great design! Bravo! Keep it up 😁

Bravo! Very, very clever.

Wow majestic Idea man!!!!! Satisfaction to death “

you are a god damn genius

Neat! I wonder if the white segments could be made to attach to another part, the same color as the seg plate, so that when the white part gets pulled out of the way, it pulls the blue part into its place, so that you don't see the seg plate at all, especially the slots. It might not be as straightforward as it sounds, since the edges of two white segments are already close to each other as it is when they are both "on", but maybe something that could be accomplished!

The obvious direction to go from here is a carry to activate the tens, hundreds , thousands ,… positions . And the other obvious is to drive it with a solenoid at 1 hertz .0166… hertz. Create a module that counts to 6, 2, and 1. 1 hertz flashing colon. Translucent segments backlit with LEDs ( yes I see the irony ). What do you think? Oh and you could do the slanted display that uses all the same segments except “c”.

Would love to see you add a "tens" window just to show how many times (maybe up to 100) it's gone past 10, with maybe a reset butting to set as default, that way it could be used more as a actual counter for tracking things...

I was having an issue where the push action plate was sliding out of the spring barrel holes. I made the pins the same length as the pin holding onto the rubber band and it doesn't slip anymore. And I would love to see somebody make this into a working clock!

Thank you.. bravo. Would love to see a 3-4 digit version (as a count clicker)
