Spannerhands Spool System mk6 Core Upgrade

Remix of the spannerhands spools system mk6 core. This one can hold desiccant on the inside and has space for 6mm bearings (or bb's) since I had issues with filament role friction in the original.


4 parts: The core, cap, and handle can be printed out of any rigid plastic. The ring is meant for TPU or some flexible.

The handle takes M3 bolts and heat set inserts.
