Yeah, it's a holder for Ryobi multitool. Four screw holes are in place for Biltema pegboard, but you can also attach this with wood screws to other surfaces. Biltema begboard has 4mm holes 12mm abart.

Print instructions

It's important to print this in the position that stl has it, to get needed strength. It's designed so that no supports are needed! I used 4 walls and 4 top/bottom layers to get it sturdy enough to hold the multitool even with battery. With print speed of 60mm/s, it takes 5h25min to print and it uses 20 meters of filament.
