Rotring 600 - magnetic case

Hardware needed: 8-16 circular magnets 5x2mm

This is a case designed for my favorite drafting pencil, the Rotring 600.

I have added a pause on layer 49 where up to 8 magnet pairs can be press fit into pockets that will then be printed over to secure the magnets in place. This captive magnet approach dictates that the user pays attention to the polarity of the magnets, because their orientation is impossible to alter after the fact.
