This is a magsafe tool holder that can store up to 12 bits with one ratchet wrench from 711L. Light weight, compact, easy to use.
To insert magnet, place a pause at the desired layer. In my case it was layer 10 (.16mm height). Then insert the magnet in the correct orientation, then continue print.
It will hold standard size hex bits. I included the SolidWorks model incase anyone want to tweak it to their desire fit.
