A simple torch holder for bikes. Designed for a torchlights that are about 27mm and 24mm in diameter, give or take a couple of milimeters. I can't program in SCAD, so it's not parametric, sorry!
Uses 2x 20mm M5 bolts and nuts. Preferably one with a thumbscrew so that you can remove your light easily without tools.
I realised I made part 1 too small, the initial one fits smaller torches about 24mm in diameter. Use Holder 1-27 if your torch is 27mm in diameter.
Part 2 has a snap on bolt, which needs to be printed with support. Part 2-0 has a hole for a M5 bolt which might be a more robust connector if you're having issues with fit.
