thingiverse
Filament spool spacer for Protoparadigm kilogram spools. Resized version of TheRuttmeister's Ultimachine spool spacers. Now available on Github: https://github.com/bld/Protoparadigm-Spool-Spacer Instructions Print two. Press fit 2 608 bearings into place. Secure with M3x15mm bolts, nuts, and washers. Put into spool. One will be inset. Put 5/16" or M* threaded rod through. Let threaded rod extend out far enough to mount in your filament support system. Secure with nuts. I wrapped the inset side with tape as a spacer before mounting in a simple T made of 1x2s.
