CTC replicator dual 28mm spool holder

thingiverse

This thing was made with Tinkercad. Edit it online https://www.tinkercad.com/things/eoTd27gB0Hp Its made up from a few different parts and can be tinkerd with if anyone wants a go. its not a complicated thing. the screw thread and the locking ring are a fixed size for the CTC replicator dual 3D Printer spool holes. I have just recieved a different size spool of abs with a 29mm hole in the middle and it did not fit any of my spool holders so.... redesign time. the spool holders only require one locking ring that is fitted from inside the printer housing unlike the spool holders that come with the printer that need 3 locking rings and that means u need to unscrew the outer one everytime you change fillament (I do it often and its a pain) so they have a nubbin on the outside of the holder instead of the locking ring, they have held this spool on so far and its just about empty.
