Rigid Ink 3kg Spool Adapter

thingiverse

This is a versatile spool attachment designed for Rigid Inks' 3kg spools, but it can also accommodate other spools of similar size. To secure the adapter to the 3kg spool, firmly twist it clockwise using specialized gripping tools until the cam-shaped adapter snugly fits against the inside of the spool. Two versions of this spool adapter are available: a basic model featuring a simple 10mm hole in its center and a more advanced version that incorporates custom-printed bearings. The latter is essentially a proof-of-concept design, but if you decide to print it, you'll also need to create six default bearings using the provided template from Thingiverse (https://www.thingiverse.com/thing:2846323). These bearings should fit snugly into the spool adapter parts with minimal effort, requiring only a gentle press.
