AAA to AA lightweight battery adapter

thingiverse

Just Your standard AAA to AA adapter that helps with reducing the weight of things like mice (in my case). You can also use it in emergency situations when you have only AAA batteries at hand :) You need: - 1x button head M3x5 screw to thread it in the hole. It's a tight fit. If it's too tight just lower extrusion percentage/ratio by 1-2% (Simplify3D/Cura) or 0.01-0.02 (PrusaSlicer).
