Cardboard Spool Container

If you have a pile of cardboard filament spools lying around like me, this is the perfect way to make use of them. This 55 gram print transforms the spool center into solid medium sized containers. I've been using mine for switches, lipo batteries, dowel pins, and lots of other small bits that usually end up loose in a drawer somewhere. The knurled screw-on lid goes on easily with a half-turn. There's a version with a label cut-out available or a blank lid if you prefer. The fit is tight, but this ensures the containers are sturdy and the base/rim doesn't slip. I've been using ELEGOO spools so far, so scaling up or down could be required for other manufacturers.
