Battery light mount for Aldi bike backlight

The seatpost clamp of Aldi/Hofer battery bike backlights has a weird hook. This thing replaces the original clamp with a cleaner design. Fits Aldi battery backlights sold between 2014 and 2017 and can be edited to fit other backlights as well. The STL file fits 27.2mm seatposts and assumes a typical a seatpost angle of 73°, but the OpenSCAD source can easily be edited for up to 31.8mm or down to 25.4mm. Uses ttwo M3 bolts (and nuts), one for the seatpost clamp and one to hold the light - I drilled a 4mm hole to the bottom of the backlight to get a better fit.
