Small Spool Extension Coupler

thingiverse

I really like tamel55's Small Spool, but I needed to load a full pound of nylon onto a spool, so the small spool was not suitable. I used Slic3R and 3D Builder to slice off the male and female parts of the spool halves in the original STL files, then fused them to make a male/female spool extension.\r\n\r\nYou simply print it and thread the coupler extension between the halves, resulting in a spool that is now twice as big!
