Printed on my Anet A6 with PLA. I used glass marbles as the beads, but I could find 12mm or 16mm way easier than 14mm, so I scaled this one down to take 12mm marbles. I also used 5mm magnets instead of the normal 6mm to make up for this. Not all of the marbles had the right tolerance, but most of them did so I ended up picking the best ones. This is the result, I think it looks pretty good!
