This is a battery box for IKEA Skadis, allowing for storage of 9V, AA, AAA, CR2016, CR2025, CR2032, LR44 as well as empty batteries. It is mounted by using the fantastic T-Nuts. It has an additional hole also for me to mount it on my existing workbench pegboard.
Print is super easy in PLA, 15% infill, 0.2mm layer height, no support, simply lying on the bottom surface.
