Description

I found this video and wanted to make my own. One nut goes on right handed and one goes on left. All overhangs are 50deg so it should print without trouble.

Update:
In case you missed it in the comments, the original screw and video were made by VeryWetPaint (http://www.thingiverse.com/VeryWetPaint).

Instructions

Print. Depending on your printer you may need to scale up the nuts by ~5% for a smoother fit (see comment from jimcook).

Fun print. I had to increase the scale of the nuts 5% to get them to fit smothly.

Cool! That's my video, so I'm glad to see it got noticed!

For easier threading I suggest you bevel/chamfer the openings on the nuts, the way you did on the end of the bolt. A beveled opening also helps disguise the trick threads by recessing them away from the exterior.

For purely aesthetic reasons I also suggest you 'drill out' the center of Nut_1 so
it has approximately the same size opening as Nut_2.

Here's a collection of screws and nuts I built trying to develop my version. I will try building your version this weekend!

Can you post your STLs of the pieces in your video?

Looks like you've gone Nuts! :)

Whew! that's crazy. This must be some kinda voodoo! :)
