Pre-sized rim that fits Duramic PLA+ spools (and possibly others - it fits all the PLA+ spools I ordered and I assume that it'll fit others as well. Runs well in the AMS, unwinding / rewinding filament without issue. This print is tight to the rim and shouldn't slip. The spools with the purple rim in the photo are the Duramic spools. This model is a remix of the parametric rim by Blizzard!
