In my spare time this summer I've been working on a mechanical braiding machine. I'm not sure where the idea came from, but one night I jotted down the design for a mechanism to braid three threads together. The design quickly went from the notepad by my bed to Blender, where it took about 2 weeks of programming (the gears were generated by a python script) and modeling to have a finished braiding machine. Then it took Shapeways exactly one week to print up the device and deliver it to my door Very Happy


When I received it, a few parts were merged together, probably because of low clearance. Both the gears were merged with their respective axles, but a careful twist got them loose. The only other assembly required was to push the top axle with the gears into position (it was left out of position so the gears wouldn't merge).

The BraidMaker worked as intended right away, except for locking up once in a while. This is solved by gently tapping the device so the pieces fall into the right spot. It also runs smoother the more you use it, a combination of me learning how to operate it properly and the track getting smoothed by the moving parts.

Some of the parts of the device are very thin, like the gear teeth (which are no more than a millimeter thick) but it is still very tough and handles being used as intended. The material is truly white, strong and flexible. When running it leaves a thin blanket of white dust behind, probably from the moving parts grinding against each other, but that is probably only while it is new.



All in all I'm very satisfied with the BraidMaker. I was expecting several parts to be merged together, the gear teeth to be too thin and therefore snap when I'd try to use it, and the device failing to braid at all. Nothing has broken off yet, and it is quite capable of braiding (thin) threads!



The BraidMaker is available at my shop for $17 in WSF.

That is absolutely friggin' ingenious! Very Happy

I do have a recommendation; do you reckon you'd be able to upscale it to plait wool (as in yarn)? You'd probably need to retool it a bit to reduce clearances, but I reckon you could have a market for it among crafting hobbyists.

I love it, brilliant idea and great modeling - I use blender and find it difficult to do accurate non organic modeling but you aced it

Very nice, I remember a battery powered braider on some commercial a while back.

amazing little contraption.
I was thinking on something like that myself but as a icing extruder (potentially just play-doh icing)... never materialized up to now though.
Hats off for actually making it, although I'm sure you can get it running smoother on the 2nd iteration.

I know the thing; my ex used to have one. Little plastic purple and blue thing, if I recall correctly. Quite scary when you switch it on; it was crazy fast! Razz

I believe it was it or something like it that my sister got here hair all knotted in and we had to cut her hair.

I am jealous of your design...

it is way too cool. and it worked the first time too! So hats off to you! Im either posting or bumping this project in the Feature This thread.

I think I really need to revisit my Transmission Project...

This is really cool, I love this sort of machine, and printed all in one too, that's great work!
