GameBoy Advanced GBA Cart Holder (Compact and fast)

thingiverse

This is a very simple and compact GBA cart holder, holds up to 8 carts. I printed this at 30% infill and 0.2mm layer height - lower settings will work but keep the wall layers at 2 or more. Designed to be a medium loose fit, don't be surprised if they aren't as snug as in a real GBA. Has little lips at the bottom to ensure carts don't fall through so can be picked up and moved.
