I needed a Ryobi Battery holder, and found one. Remixed it to use less filament and use the skadis t-nut system for M2.5 : https://www.printables.com/fr/model/228663-skadis-t-nuts-mounting-system-for-ikea-skadis-pegb
Printed in PLA (upside down) without supports, 0.3mm layer, 2 perimeters, 15% infill
Tested with a 5Ah battery, I don't have a heavier one.
The author remixed this model.
