Small spool dimensions that this handles: OD = 150mm, Width = 38 mm, spool walls thickness = 4.5mm (other dimensions unimportant) There are other adapters, but here is why this one is the best: grips the outside of the small spool wide stance in the ACE/AMU for best reliability A grippy tread on the outside of the spool means this works when printed with PLA (which is perhaps more slippery than other materials) steers the filament back onto the spool when retracting Provides a hole for the end of the filament to rest in Minimal material usage
