love it! just one suggestion: a bit of paranoia when sucking up sparks won´t hurt, especially if you use your shopvac for wood dust too. the hose you you connect is pretty big, so relatively low air speed (for a shop vac) = more time until hot stuff ends up in the bucket/filter. that´s a benefit. longer hose cant hurt either... but I´d suggest some sort of spark trap could make a for a good FPF video too ;) all the best, don´t burn your shop down. :)

I pulled the trigger on this several months ago. Use it all. the. time.

@tehhamstah 5 месяцев назад

Look up a video by MakersMuse called "How to 3D Print bores without supports" - I've been using this technique ever since I saw that video, and it works like a charm.

@deadly_dave 5 месяцев назад

Ha ha ha, came here to say the same thing.

@therick0996 5 месяцев назад

Yep. Adding little squares and cut extruding by 1 and 2 layer heights is great

@rlamb007 5 месяцев назад

I have the same sharpener and love it. Will definitely look at trying this out. Thanks so much for sharing.

@chriswisneski6071 5 месяцев назад

Nice upgrade!

@jpmmaio 5 месяцев назад

For the "upside-down" counterbores, i keep a 0.2mm (or whatever is the printing layer thickness) on the bottom of the counterbore. You can imagine 2 blind holes facing each other separated only by a layer. Print without any supports. It will bridge the bottom of the counterbore easilly. Then it's a matter of drilling out that layer. It does not make a extremelly perfect hole, but there is no messing around with supports. Also works with other type of features, where a single layer brigde works better than the supports!

@billdoodson4232 5 месяцев назад

I have been looking at buying one of these for a while, but they never come up on the UK Vevor website. If I do get one, the shop vac attachment is a really good idea. I think that I would print 4 new taller feet in TPU to get a better outlet path and for my use put the outlet port on the back. A really good idea that seems to work well.

The reason for the tiny particles left behind is the high velocity air moving creates static electricity charging the steel casing.

@FunctionalPrintFriday 5 месяцев назад

thx! I love understanding stuff like that.

@ejcatmul 5 месяцев назад

You could use a helper disc built into the cad model or within the slicer at the shoulder of the bolt hole and then you won’t need to use support make the layer at the shoulder just like .2mm and then you can just drill through the .2mm for clean concentric holes printed vertically. Sorry if I didn’t explain it very well.

@sypernova6969 5 месяцев назад

hey! great work as usual. one thing i'd add, is, and i thought hte same on another video where you designed air channels, you should do fillets in the corners so that the channel/duct is as round as possible and the air can follow a smooth path, instead of having to hit 90 degree corners, or to go hid int he corners of rectangular shafts and create turbulence.

@haydenc2742 5 месяцев назад

Good stuff...definitely a useful upgrade...gonna need to grind up alot of drills to really test it out! Keep em coming!!!!

@FunctionalPrintFriday 5 месяцев назад

Thx. Always appreciate seeing your comments.

@PDXN8 Месяц назад

⁠⁠Great vid - subscribed! I don’t have a 3D printer - would you sell one of these dust ports?

@AlexSwavely 5 месяцев назад

@18:50 instead of supports, add a single-layer-thick solid layer at the bottom of the counterbore - it'll bridge just fine, self-supporting the rest. Just punch it out after. iirc, SuperSlicer will do this automatically, but anything else you'll have to do in the cad model.

@dwp6x9e42 5 месяцев назад

I think I would have gone with a base under the hole thing where the feet fit in snugly. I would then put a drawer for dull bits underneath. You could then add some small air chanel slots underneath to the side and front.

@rhost714 2 месяца назад

There are two holes under the front cover for the allen keys

@Neslekkim Месяц назад

Do you have step file for this?, I was thinking about changing the hole so it fits my vacuum (35mm-ish), and my M13B came with extra grinding wheel, so I was thinking about adding an pocket to store that also. It might be a bit much on the backside but..

@trippinonaduck1379 5 месяцев назад

For flat counterbore holes that don't need supports, you can us a technique like "sequential bridging" in Makers Muse How to 3D Print bores without supports (Fusion 360 Masterclass). Pretty simple to print and leaves good holes.

@kizzdevaughn46 5 месяцев назад

Like your videos 😊

@andyshap 5 месяцев назад

What kind of glue are you using?

@FunctionalPrintFriday 5 месяцев назад

3d gloop for PLA. Pricey, but it does work better than anything else I have tried.

@osumailguy 5 месяцев назад

Ref removing the fan ... I'd be a little concerned about the possible change in overall balance if that was done - it would obviously be minor, but potentially still there.

@heidi5942 5 месяцев назад

I also wonder if the fan is also acting as an air governor to regulate the speed?

@FunctionalPrintFriday 5 месяцев назад

The wheel itself *should* be balanced. I would think if anything the fan might cause a slight imbalance. It's possible they put the heavy spot on the wheel opposite the heavy spot on the fan, but that sounds like too much to expect for this tool. Fwiw, it does run pretty smooth. The motor looks like a smaller version of what you would find on a treadmill.

@TheDisorderly1 5 месяцев назад

My dad had a fire in his shop vac one day from one of his woodworking tools. Just be careful.

@ajosepi1976 5 месяцев назад

For better printed screw holes without supports watch Makers Muse video "How to 3D Print bores without supports (Fusion 360 Masterclass)". He explains it better than I could in text.

Not sure what you are grinding, but that is a diamond sharpener. The amount of metal you are removing from a drill bit should be small. I have this drill doctor, and it works great, and no appreciable “dust”. You might be creating a solution looking for a problem. Unless you grind a whole heck of a lot more off your bits than I do, of course. It’s nice to watch your process though.

@FunctionalPrintFriday 5 месяцев назад

It's a CBN wheel. They do include a diamond wheel as well for doing carbide, but the CBN is what I'm running.

@torchmd 5 месяцев назад

My apologies. But still. Cbn is even better. I guess if you were grinding a hundred drill bits a day, but still, it’s a drill bit. Sharpening is just taking a couple thou of. Maybe less. I find it’s nice to be able to touch up a drill bit before use. I’ve never seen any appreciable dust. I know, “it’s the dust you can’t see you have to worry about”. But it ain’t much. Do you have dust control on your grinder? Not that produces some dust! Out the angle grinder? That slings some dust! The drill bit sharpener? Meh Still. Fun to watch. But a lot of work for little return. 🤷🏻‍♂️

@FunctionalPrintFriday 5 месяцев назад

@@torchmd actually I do have dust collection on my grinder: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-_zljH6C7hTg.html The angle grinder, no. I try to take stuff outside if it's not raining, but yeh if I run that in the shop, it gets stuff everywhere. Admittedly, it's not an achievable goal to eliminate dust, but ever since I bought the lathe and it's fresh in my mind just how much one of those costs (it hurt), been doing my best to keep any abrasive dust off the lathe ways when it's avoidable. Thx for your comments and feedback. It's always welcome, even if you're challenging something I've said :)

@TS_Mind_Swept 3 месяца назад

Not sure if someone already mentioned it, but conical screws are really bad for 3D prints since they apply a splitting force to them; obviously truly flat top holes are impossible to print, but there are a few solutions for that out there as well that don't involve adding a support structure (I also like to make small test Prince when parts I'm making have to interact with each other that consist just of the areas that are interacting, that way it takes less time and material). Not sure if you already knew any of this, but I just wanted to say; printing stuff for random things like this is always fun :p
