I made this Springy spool adapter for crealite printer but should fit any 36mm shaft. I slice this part 101-102% to fit bigger than usual centers and in pairs. The part could be reduced or enlarged at your convenience or need but should not be more than 2-3%

The part can be printed with PLA, PLA+, ABS or PETG as will be your preference.

This part belong to the new filament pack as shown in the picture.
