Magnetic Bit holder

5x, 8x, 8x (fits Gerber Centerdrive) and 10x. The Gerber Centerdrive version is 2mm lower. 

You need 5mm round magnets.

Print without support. Insert magnets and push in the stopper. I have made four different versions of the plugs for best results. If it is cramped for the bit, you can scale up the holder, with the stopper to get a better result for your printer. Of course, it is also possible to glue the stopper for a more permanent result.

Let me know if there is something you want to change or something is wrong.
