Can we make a binary counter using only 3D printed mechanical parts? Yes! Follow me on my journey to figure how to this with a Geneva mechanism…

Wanted to do a longer devlog on my process finding this design. How does one design a connector that allows you to rotate 180 degrees and it still connects? (But not at 90 or 270 degrees)

You may have heard that bees use hexagons, but did you know that’s not the whole picture? There’s a 3D shape called the Rhombic Dodecahedron which is actually the shape they use, it tiles 3D and is technically also a projection of the hyper cube I made a 3D printed magnetic toy based on this!

I also tried making a little board to put them on, inspired by some wooden toy thingy, and it’s fine, but I don’t find it is needed. Afaik there’s another different lattice u could do more spiky

Anyway the design and files are here for free, feel free to print them yourself if interested makerworld.com/models/1851142

I later just found a supplier of thicker magnets (stacking two magnets=1 thicker magnet) and this improved strength a bit more. Here’s some various colors I tried, 3D printing is fun :3

I also made a standalone dodecahedron piece, this decreases magnets needed relative to 4 smaller pieces

So I picked up some stronger magnets, and… it worked okay. Def better, but I felt it could be improved

So I decreased the size as much as possible, and stacked each magnet two high (so there were eight magnets per face). This paid off, the connections were very strong now!! Longest supported bridge test (green is new design)

It worked, but, the magnets were too weak and it was a little frustrating to use

So I tried eight alternating magnets, but that didn’t help much because the size counteracted any of the gains from more strength

*size Okay, so next thing to try was smaller magnets. I picked up these little disk magnets

So I excitedly made lots of pieces and inserts (had to play with the depth until it fit in snug), and…

So that resulted in this chungus pieces, but they were too large and so the mass of the PLA+lever (the larger the more dist between connections) meant they weren’t very good to use

I tried decreasing the side but the inserts then overlapped causing this problem

So I thought, let’s do four magnets instead, in this pattern. Alternating so +- -+

That was a lot of magnets so I made these little annotated test pieces to see if I could get away with 2 or 3 magnets instead of four. But it seemed like the strength lost was too much and it wasn’t worth it, and I needed to do four

It was easy to embed it at the top and bottom, it was the sides that were especially annoying. So I thought I could just print these little PLA boxes around the magnets…

Then I could insert them into the piece. This worked, and even let me attach two pieces together only at 0 and 180 degrees! Unfortunately it was gendered, M-F worked but M-M or F-F would be 90 degrees and 270 degrees instead.

So it starts with these little guys, it’s a snap fit connector. This works alright, the bumpy side is the face with supports. A later design had one face open to make it less bumpy on the bottom

But I wanted to try a magnet thingy, so I started with this design. Basically, I would insert these bar magnets at various points while printing, then it printed over them and sealed them into the piece This was very tedious and if they weren’t snug enough they’d just come off and attach to printer

Due to popular demand, here is a demonstration video of how to make 3D printed PCBs using just vector drawing software, a 3D printed (PETG filament for mine) and self-adhesive copper tape. Any questions, let me know!

castpixel ⚧️⚢@castpixel.bsky.social

I made a tool that turns PCB designs into 3D-printable molds. you sandwich copper tape between the parts, sand the ridges, and you have a real working PCB. no etching, no chemicals. I am losing my mind castpixel.itch.io/pcb-forge

The key is to, ultimately, make reciprocity a winning strategy rather than something enforced by all agents valuing it, that's alignment at the level of social organization rather than individual minds and, obviously, it's far from trivial.

Wheres the theft? They bought the books. They legally purchased them with money. Its beginning to suspect you dont know what theft means. Also youre literally showing the same process Anthropic used.

Understandable

jimray-bsky.leaflet.pubLet’s Build an Atmospheric WebThe Atmospheric Web shows we don't have to accept the false choice of ownership vs. distribution

Is an interesting point: - old web had ownership but discoverability was bad - new web has no ownership of data but discoverability is better Bluesky lets u do both, showing it wasn’t really a tradeoff after all I do think anyone being able to make algorithm is important part of it

This is the most succinct version of a post I've been trying to write for two months. When I stop for just a sec to think about the possibilities of The Atmospheric web, I'm a little overwhelmed by how exciting it is. Come build it with us!

My marble elevator (well really, ferris wheel) works!!

12 Dec 2025

It prints in two pieces, the marbles fall into the holes and then once they reach the top they’re flipped so they fall out

12 Dec 2025

This is not a particularly practical way of elevating the marbles, but that’s ok. I wanted something where each of them get their own little “car” they ride in, and I think this does that well :)

Off to the races!! This is my first racetrack run with my 3D printed tiny marble set, it works!! :) :) :)

Workin on a finish piece for my marbles, a thread:

This one I’m pretty happy with and works fairly well however sometimes marbles come out at high velocity and bounce off an existing marble in track and escape, adding fins to catch them…

This is fins design, I think it looks cool, kinda like an insect/eleytra, will need to wait for start piece(!! So excited) to finish printing before I try it
