Rigid Ink 3kg Spool Adapter

thingiverse

This is a spool adapter for Rigid Inks' 3kg spools although they could fit other spools I'm not sure. This attaches to the 3kg spool by twisting the adapter strongly in the spool using some gripping tools. The cam shape of the adapter will tighten against the inside of the spool making it very secure. There are two versions of the spool adapter: one with a simple plain 10mm hole in the centre ('Rigid Ink 3kg Spool Adapter') and the other is special in that it uses some of my printed bearings ('Rigid Ink 3kg Spool Adapter 40mm Bearing'). The version with the bearings is probably not really any better than the plain version; it is more of a proof of concept. If you do decide to make that version, you will also need to print 6 of the default bearings found here. https://www.thingiverse.com/thing:2846323 The bearings should press fit into the spool adapter parts (three in each piece)
