Wall Control pegboard holder for Allen Key Handle made by jairsinho. Uses four embedded 8x3mm round magnets for most of its holding power. Nubs on the back help line it up correctly with Wall Control pegboard (~25.5mm center to center) and keep holder level.

If you need details on pausing prints to embed magnets using Prusa Slicer see the Prusa article here.

Included f3d file for easy modification, have at it.
