I wanted to use a cheap, old mini tripod as a bipod für my crossbow and searched for an adapter to attach the tripod's screw to the picatinny rail. The ones I found either had a printed plastc thread or were otherwise unsuitable for my needs. I then found a nice genereic picatinny clamp, modified it a bit to better suit a M3x35 screw and added the recess for the 1/4 nut.

Print with 100% infill. I used PETG, but ABS will certainly work as well. You will need the following parts:

• 1x M3x35 screw
• 1 x M3 nut
• 1 x 1/4 UNC nut

Enjoy, give the project a Like and tip me if you really like it.
