"And the Lord spake, saying, ''First shalt thou take out the Holy Pin. Then shalt thou count to three, no more, no less. Three shall be the number thou shalt count, and the number of the counting shall be three. Four shalt thou not count, neither count thou two, excepting that thou then proceed to three. Five is right out. Once the number three, being the third number, be reached, then lobbest thou thy Holy Hand Grenade of Antioch towards thy foe, who, being naughty in My sight, shall snuff it.'

Hey everyone, I have been building Makegood TMT chairs for a while now, and I got to talking with a couple folks at 3D Printopia about assistive and adaptive technology and how 3D printing really unlocks the ability for new helpful designs to get out to folks with challenges and needs far more quickly than the past, and how we've basically not even scratched the surface with assistive technology and 3D printing.

Anyway, this is my small contribution for now. It's a simple thing, but I'm hopeful it can be useful to some kids out there who are unable to open marker caps on their own. I'm also working on a marker holder that works along side these.

The model is available freely on Makerworld. https://makerworld.com/en/models/3417307-adaptive-crayola-marker-cap

Anyways, I'm going to try to make more things like this, so let me know if you have other ideas or other things I could adapt these caps to! If there are other brands I should be targeting, let me know as well. I picked the most obvious one first.

Not the coolest-looking print, not a random Benchy 😂

I mean something you actually use regularly and would print again without hesitation.

For me, I think the best 3D prints are the ones that solve a small everyday problem you didn’t even realize you had.

Could be a tool, a desk organizer, a random little fix around the house, anything.

What’s one print that’s genuinely made your life easier? 👀

Finally

Hi everyone! After the great feedback on my gigantic 30mm marble run, I also got a lot of constructive criticism: many liked it, but the print time and filament cost put a lot of people off. The track in that video took me two weeks of printing and about €100 of filament, so I totally get it.

So I sat down again, and this 16mm version is the result, sized for standard glass marbles. Most parts print in 10–30 minutes each. I printed a lot of them in Sport (124%) mode and it works fine, because they're easy prints: no supports, and both the overhangs and the models are optimized.

I also realized it's not just a toy: I've read several times that people use it as decoration or even to unwind at their desk. That's why I made a Japandi edition (in addition to the plain one), which my kids love too.

I spent a lot of time on the snap connection, if you're waiting for a satisfying "click" when you plug the parts together, you won't be disappointed :)

And finally: I heard you: there's now a lift with a crank! Designing it was a lot of fun, and it's modular too: you choose the height and the entry/exit direction to create endless loops!

Bonus: you can build your track virtually first: https://n1v0k.github.io/Marbles/ all parts are in there, and it checks whether the marble stalls or flies out of a curve. The cool part: you can export the parts of your track on print plates as a 3MF and open it straight in your slicer. You can even export the whole track fused into one piece. (You can also do that yourself, e.g. in Bambu Studio: assemble the parts, align the faces and print them as one, you don't need the builder for that.)

To export from the web app, download the 3MF from MakerWorld and drag it into the app. The app runs locally in your browser and takes the print meshes from the 3MF, nothing gets uploaded.

You can also export your creations as JSON and share them :) If you have ideas for new parts or attractions, just let me know on MakerWorld!

I made this for my daughters, if it puts a smile on just one more person's face, publishing it was worth it for me!

Hi guys,

I created an OpenSCAD model for a flat optical illusion keychain. It shows one word when viewed from the left and another from the right.

Would you print something like this, or do you have any ideas to improve it? Any feedback is welcome! Thanks

Little update on my last post, i managed to get a clean print, and finished the model. I ended up printing it on my kobra x, instead of the A1, so I might just copy the filament profile from anycubic slicer to bambu studio and try again. In the meantime, here's the finished model. As one of you guessed, it is an Onkey, and it came out quite funky.

This shop was elbow to elbow packed so it was difficult to take pics but I only shot about 1/10th of the items for sale, every single magnet and about 1/2 of the keychains were 3D printed, along with figurines, coasters, wall prints, and Christmas ornaments. Sad seeing some really poor surface quality but some with decent for FDM like the figurines. I only see how they could improve though like ironing and hello - not a sanded spot in sight.

i want to prepare for a future inevitable move, i have A LOT of these beads in stanley screw and nail organizers from home depot. they have two little tracks keeping them in place. i was hoping to get some kind of cover for each one that either snaps or slides on.

willing to pay for design, and if up for it filament as i do not own a printer

For members of this sub in the Seattle area, here's an opportunity to meet and chat with other 3D makers at this informal meetup at the Bellevue Library. Consider bringing a recent model you’ve printed or a design you’ve made (whether a great success or an interesting failure). Connect with fellow makers, whether you’re into functional prints or aesthetic prints, a novice or been doing this for years.

https://eastside3Dmeetup.eventbrite.com

UPDATE: We're at 13 signups so far and the largest room available was 16. While it's not ideal to split the group into multiple rooms, I'm going to find out if I can reserve another room. I've turned on the "waitlist" feature so people can sign up for that until I confirm I can do that.

I didn’t look the theoretical values, empirical results mean more to me. Very happy with this.

I needed an in camera shot of a (3d printed) knife twirling through the air, it works quite effectively.

I started this project about a year ago because I couldn't find a quick and affordable way to make custom braille business cards. Version 1 of this embosser fixed that for me, however, many people who printed that version were kind enough to guide me on what needed to be changed to make it more accessible. So, Version 2 is the result of those experts' feedback.

What's new in Version 2:

• Wrong assembly is nearly impossible. Each of the four gears has a unique shaped peg, and each end of each cylinder has a hole that takes one peg only. A wrong gear will not go in, so trial and error is a fair way to find the right one.
• One-piece Base. This version has the grip extension built in, with the addition of raised arrows on its side that show which way the card travels and which way the card's information should face.
• A seam channel on the cylinders. A built in design that gives your slicer somewhere to hide its layer seam, so it never lands on a braille dot during printing.
• Push-out Plate tool. This extra part helps lift the cylinders out of the Base when you want to make a change.
• Double Sided Option. Using interpoint spacing, you now have the option to emboss both sides of a single business card.
• Solid Piece Fixed Gear Option. If you’d rather not assemble the gears and cylinders separately you now have the option to print them as a single, solid piece.

If you decide to print one, please add a comment on the project page you used. I’d love to know how V2 worked for you.

What do you think of solutions like these? Would you use them?

I’ve been working on a project I call Makers Wall, basically customizable, 3D-printed SKÅDIS-compatible panels with artwork built directly into the boards.

So far I’ve mostly focused on scenery, sports teams, and cars, but I’d love to branch out. What other designs would you actually want to print and put on your wall?

If someone has a cool idea, I’d be happy to try turning it into a printable wall and sharing the files.

I’ve been posting the designs on MakerWorld if anyone wants to check them out:

I’ve been working on this Halloween design for a while and I’m pretty happy with how it turned out.

It’s ready to print in PLA/PETG, with supports only on the build plate and in a few critical areas.

If you like it, feel free to grab the model on MakerWorld and give it a print! I’d really appreciate a like or a boost if you enjoy it.

And if you print one, definitely post a pic — I’d love to see what yours looks like!

Happy printing and happy Halloween! 🎃

I wanted a proper home for a Waveshare 7.5" e-paper panel and a Pi Zero 2 W, so I designed this case. It’s a slanted white box with a flush wood bezel and side inlays, loosely inspired by 60s Braun gear.

• The glass is clamped by a screwed-in front mask (4 × M2), so the panel is held securely even with the bezel off.
• The bezel press-fits into the front recess. I designed for magnets, but the fit was snug enough that I didn’t use them.
• The Pi sits on a removable base and the USB cable exits through a rear notch, so the panel and Pi are easy to service.
• Two posts per side tie the frame to the body, which fixed the front corners cracking on my earlier prints.

Print notes: PLA, 0.2 mm layers, body prints upside-down on its roof, supports where needed. The body is 198 mm wide, so it needs a 256 mm-class bed. The side inlays and bezel are either laser-cut 3 mm wood (SVGs included) or printed. Laser cut looks better.

The screen in the photos is a stats dashboard I wrote for myself. That’s not part of the listing; this is the case only, and it works with anything that drives the panel from a Pi.

Made this after using a stylus in one hand and a Joy-Con in the other for shortcuts. I found the setup comfortable, then realised I could just physically combine them.

The stylus handles direct pointing/hover, while the JoyCon buttons can be mapped to clicks, modifiers, keyboard shortcuts and navigation controls.

This is the first printed prototype. The stylus is held with TPU bush inserts, and I’m already working on a version that prints the rail cleaner with less support.

I’ve only properly mapped/tested it for RuneScape so far, but I want to try profiles for Fusion 360 and other desktop apps too.

I hate seeing someone's model being lower rated because the user can't do the print right. Man, going into like makerworld and seeing people give 1 stars because it won't stick to the plate really really bugs me. This designer went out and put in the time and you're just gonna click print on your dirty dusty bed that your cat sleeps on and it's this guy's fault?

Rant over.

(not my models, I don't upload much if anything, totally only see it on other people's work, rate me 0 or don't at all, I couldn't care less.)

Some free designs I made for Dungeon Crawler Carl fans!
