608 ZZ Bearring Spacer for 5mm threaded rod Spool Holder

thingiverse

Sometimes a spinning spool would catch onto the nut and thread it in too tightly, causing the spool to jam and cease spinning altogether. The printer itself had also recently lifted out of its cabinet and crashed to the ground due to this issue. To prevent such mishaps from occurring again, I designed these bearing spacers which allow the spool to spin freely even when the nut is tightened securely. These spacers are intended for use with a specific type of spool holder that accommodates spools with diameters ranging from 52mm to 5mm.
