Minimal Spool Holder
Description
This was inspired by an obvious fail of using this part for a fidget spinner with a gear as a central pivot (works only with three outer gears, otherwise the center falls out...). Anyway, this prints very fast and does the job of holding the bearings for a spool holder. I recommend placing it on a sheet of sand paper or rubber to avoid moving because the contact area is also minimal. Created using sc.scad courtesy of Rudolf Huttary, Berlin 2015 as well as 2D fillet.
