1kg Spool Holder with Gear Bearing
by daprice, published
For using a non-printed plastic spool with tjhowse's printable spindle. This one is sized to fit a Makerbot/Ultimachine spool with a ~52mm hole, which seems to be a fairly common hole size for 1kg spools, but the parameters can be edited in the scad file to fit others if necessary.
Print this and attach it to the original spool spindle with the flange towards the base of the spindle. Insert into hole of filament spool so that the spool rests on the flange.
If it prints out with the gears fused together, increase the tolerance in the included scad file (default 0.2).
