K8200 spool nut

This spool nut is a modification of the "Spool holder for K8200" from nibblernibbles user. I use a standard 4 1/2 inches (around 115mm) lamp screw with two (2) nuts. This way you just install this on your spool and put it on the original spool holder screw of the K8200. The original nut design create some resistance and this way the spool rotate very freely.

If you change filamente while printing, like me, just print more nuts and buy more lamp screws and have your filaments spool ready for
