M12x1.75 Bolts and Nuts

I finally learned how to make proper knurling.

I plan to make multiple sizes just because I enjoy making them.

This actually make great and silent fidgets. :)

• After a test print, I decided to take the knurling all the way to a point.
• Version 2 has a larger chamfer and coarser knurling.
• Version 3 has the proper size hex socket... it should NOT match the shaft size :)
• Version 4 has better fit on the hex socket (slight taper)
• Added washer
• Added sets
• Clearer file names

Feel free to send me a message if you have any special requests.

Notes:

• I recommend at least 3 shells/outlines
Nuts are pretty strong at 10% Botls, especially longs ones need higher infill Having a cheap tap and die set can help you make these work better.
