Adapter for det Esun cardboard filamet rolls, fits the dryerbox of the Qidi X-max 3. Ø54mm outside, Ø51mm innside. I had lots of problems that the filamentroll got stuck inside the box, resulting in failed prints. This adapter lets the roll have plastic roll against the plastic inside the filamet dryer box, makinig a smoother turn. the flange makes so that the filament wont trap itself against the lid, cousing trouble.

may fit other printers, added .STEP, and its on Oneshape.

Print 2 and press them in from either side.
