EarPlug KeyChain

I saw a bunch of earplug keychain containers here on Makerworld, and since I'm a perfectionist, I always had something to complain about the designs. Mainly it's that most designs are exported at a lower resolution that bambu printers can fabricate, so I had to desgin a high quality one. Hence the massive 3mf/stl files. Vertices count. The walls are 2mm for stability. Needs to be printed at 0.08mm so the fine threads turn out nice, and give a great feel when un/screwing the container.
