Kobra S1 ACE pro Adapter

This makes it possible to use smaller-diameter filament spools for printing; an adapter ring is no longer required. Simply remove the old spool and metal rod from the back of the ACE, then insert the two newly printed spools (including the rod). Small spools now have a small clearance at the bottom, while large, standard spools still have enough space beneath the cover. The original spool is shown on the left, and the replacement setup on the right.
