This is a lock holder I designed to attach my Abus U-mini lock to my bike while I ride it. It's meant to be screwed in place of the bottle holder, on the frame (screw holes are 62.5 mm appart center to center, and 6 mm wide). It was inspired by Dangerrapp under saddle holder.

There are two versions of the stl files, one to print the full model, the other in two files, to print the bottom and the top parts separately, in order to avoid overhang issues while printing the side holes.

It's probably best to print at 100% infill.
