Simple remix of the spacer that is intended for use with new sunlu 1kg and 250g spools. It's designed to work with makerworld.com/pl/models/653121-ergonomic-spool-adapter-for-a1-mini adapter (or other with the same diameter). The Ring width was changed to 13mm for 1kg and 43mm for 250g, which gives around 1mm of free space for the spool to move freely.
Each variant is on separate plate.
0.2mm layer, 2 walls, 5% infill
