Sunshine Reusable Spool Bambu

Improved version available: I've created a slightly improved version with a built-in filament holder/tunnel. Check it out here: https://makerworld.com/en/models/628478#profileId-553125 YABS - Yet another bambu spool. I simply designed my own infill and subtracted it from the original design. This design uses much less filament than the original, but is still very strong. My profile uses 4 walls for strength. If you're using an AMS light, I'm sure you can get by using only 2 walls.
