Giiker Super Slide extra pieces holder

This is a holder for the extra pieces that come with the Giiker Super Slide.
It has places for magnets, so the pieces slide in the holder just like on the actual board (you could just print a bigger holder to replace the original board).

I used 4x1mm round magnets, they're strong enough to hold the pieces but not too strong to make them hard to move. I wanted to place the magnets without gluing them, so they rattle a bit, but they kept twisting and moving and getting the polarity to align without the glue was difficult, I had to remove and replace the top panel a few times.
