10mm Spacer for Ender 3 filament holder

thingiverse

This is a 10mm spacer that has a 34mm inner to fit over the Ender 3 spool holder it was made to use with conjunction with the spool inserts by kenlaires They can be found here https://www.thingiverse.com/thing:3101884 I found that the inserts were good but the spools I used were not wide enough to stop them coming off the spacers. this fills up the void between the nut and the spool.
