It's a bit overengineered box for storing 8 pairs of earplugs in hopefully aesthetically pleasing way. There are 8 magnets to keep the sides toghether - 4 on each side, but of course you odn't have to add them in. The original design is for 2x2.5x5mm magnets but it should be easily editable. The two halves are attached using filament string. It can hold earplugs that are up to 13mm in diameter and 26mm in length, but they are squishy anyway ;)
Layer height: 0.2mm
Wall thickness: 1.2mm
