Esun filament roll adapter

I had lots of printing problems with my X-max 3, untill i realized that it was the cardbord filament roll that was cusing all the trouble. So I made an adapter that fits inside the filament roll that slips over the orignial filamet holder of X-max 3. May fit other printers, outside Ø54 inside Ø51

Print 2x and press them inn from either side.
