URA - Universal Roll Adapter

thingiverse

This is a Filament Roll adapter that will fit on the OEM Creality filament roll holder without modifications. Chucks on Adapter will help to center the rolls and keep them from shaking sideways. Groove inside Adapter will drop over wide end of OEM holder. This keeps adapter in position. Adapter consists of 6 parts: 1x URA_core 1x URA_nut 2x URA_cone 1x URA_spacer_short 1x URA_spacer_tall For most 1kg filament rolls the short spacer should work. Smaller rolls or rolls with a larger center hole, the tall spacer should be used. If an other size should be necessary, there is a drawing with inside and outside dimensions available above. Threads on Core and Nut were printed without supports to make cleanup easier. Groove on inside of core was printed with supports, but require fine pliers in order to remove.
