Variable Diameter Bearing-using Spool Holder

thingiverse

This vertical spool holder rotates on two 608 bearings, requiring mounting onto a surface and is removable for spools of various sizes. Attached using a key system, it fits in a base and works with the I.S.A.A.C. 3-D printer shell. Print all parts along with bearings, bolts, and threaded rod for assembly. Mount on a vertical surface, add the cap, and insert M8 rod that rotates freely. Attach spoolholder base to the rod, then secure it onto the holder. For size changes, simply unscrew the holder from the threaded rod and replace with another.
