This design is a customized version of the wall mount for Makita V18 battery, tailored specifically to integrate seamlessly with IKEA Skadis boards. Note: The hooks require support structures. I suggest printing this part with 3 perimeters.
From my experience, the 4 hooks provide enough friction to keep the battery holder in place, but if the holder tends to slide out of the pegboard holes when you retrieve your battery, consider printing the IKEA Skadis Lock Plug in 11mm I attached. Depending on your print settings, filament and board, you might have to choose another size. Please be aware that you must utilize the flat variant without a handle.
I am constantly developing more IKEA Skadis attachments. Check out my IKEA Skadis Collection here.
