Multischleifer sandpaper holder

Inspired by The Swedish Maker, but adopted for my sandpaper shape.

Using a M8 threaded rod together with 2 nuts to connect them. And 6x3mm Magnets for the containers (2 each) and top bottom (1 each) to lock it in place.

I used the support material just for the screw holes (top and bottom part) and the numbers.

If the fit for the inserts is too tight just use a drill or knive to make it perfect.
