CR-10 Spool Spindle Bushing
thingiverse
I spent some time looking at spool spindles to centre my filament spools to reduce friction and tension, but in the end decided to keep it simple. Here are a couple of spindle bushings to pack out the standard 35mm CR-10 spool spindle to 51mm and 72mm. Both are loose fitting. 51mm works so far for eSun, Eryone, Tech Outlet and Real Filament spools 72mm works for Sunlu spools
