M3D Spool Adapter w/Bearings
thingiverse
I use a 5/16" threaded rod to suspend spools above my M3D Pro printer. The 5/16" rod is securely attached to the printer using a customized version of a design from user urish, which can be found on Thingiverse at https://www.thingiverse.com/thing:2383517.\r\n\r\nWith this spool adapter, along with two 608 bearings and several nuts, my filament spools move freely and smoothly. I believe that since implementing this setup, I have not experienced a single print shift.
