thingiverse

This is an all-purpose screw spool hub designed specifically for 8mm rods. It's compatible with every type of spool I've encountered so far.\nUpdate: The design has been modified to fit 60-20mm spools as well.\nUpdate: The threads in the nut part have been corrected, and a new 200mm threaded rod has been added that can be used with two nut parts for wider or multiple spool applications.
