Batarang with magnets and holster

Batarang that uses 6x3 magnets to interface with a clip

Added slots for 6x3 magnets, just pause print before it extrudes over the holes and insert the magnets, hole is just big enough that your printer doesn't have to be perfect, yet there is no noise when you shake it.
I also made a clip that has the magnets in the same place and you can attach it to a thin piece of clothing
