Filament Spool Retainer

thingiverse

This is a Custom Filament Spool Spacer I designed specifically to ensure my spools remain perfectly centered on the holder, eliminating the frustrating issue of them running away at times. To achieve this, you'll need two spacers - one for each side of the spool. With these in place, filament spools now uncoil with a much higher degree of control. The center holes are precision-cut to accommodate 16mm dowel or rod, while the 'cones' are tailored to fit filament spools boasting hole diameters between approximately 30mm and 60mm. Additionally, I've included retention blocks that can be slid onto your rod or dowel, providing a secure fit in case the cones tend to slip off due to a loose fit.
