NEW Version is HERE \o/ Changes in the tip, now it holds a nut with 6.9mm OD, maybe a M4, not sure about the M size :-) long lasting than full ABS. Tip, if you find some brass nut, will be even better. Added a new large washer for spools with big holes. Added wings to the nuts to easily hand tighten them. Tested with ABS and PLA seems to work just fine with both. The V1 con be found here: https://www.thingiverse.com/thing:2072865 Taken from https://www.printables.com/model/211663-clapton-wire-maker-v2
