Description

This bolt allows two different direction nuts at the same time. It makes an interesting fidget toy.

Print instructions

The bolt was made after seeing this video:

And while it's a lot nicer in metal, the 3d printed variant still is nice to play with. I printed with 3 perimeters and no infill except for the bolt head. See the 3mf file.
The 3mf has extrusion multiplier set to 0.98 for filament.

Print was done in Prusament Galaxy black in 0.2 mm layer height.
After printing the nuts need to be moved a couple of times and I applied a few drops of olive oil to make the nuts run smoother.

Clearance between the parts is 0.15mm

kinda massive but it printed fine I suggest using the 50% size to save filament and time

Other Issues:Sorry but i gotta change my rating, parts don't fit there is zero clearance.

@Gijs

I’m sorry to hear that. If they don’t fit then something could be off with your printer. the tolerance is tight (.15mm) it could be that one of the belts is not tight enough resulting in ovals rather than circles. This model has been printed successfully by thousands of people. but some have suggested to print the nuts at 101% it takes a bit of effort anyways to make them start running. a bit of oil or better graphite powder can help.

@user_718106922

problem is you shrunk the file making the tolerances too tight.

Replying to @user_718106922 :

you should run calibrations .15 is perfectly achievable tolerances even for an old ender 3.

I used mate pla, I think the best one is basic pla, mate pla makes it stick

Thanks for the review and feedback! I haven´t even realize there´s that difference between matte and basic, so thanks for sharing - will have to keep it in mind :)

printed on a P1S in both black PLA and green PETG. both printed really nicely. just took a little playing with to get them to move smoothly. very nice print.

Nice print. Came out well in PLA silk+ titan grey. Took some time to break in but worth it. Very cool to see how the nuts rotate in opposite directions. Very fidgety.
