Geomag magnetic sticks and balls box

thingiverse

I built a small box with a sliding lid that clicks shut to keep the balls from rolling all over the floor. It can hold around 40 balls and about 70 sticks. The lid is pretty snug, but I always give it a bit of sanding before using silicone spray on the sliding parts - that makes it perfect every time. You might want to try printing the lid at a slightly smaller scale, like 1.01-1.014 times normal size (101-101.4%). Everything should print without any supports needed.
