Just a minor modification to the diameters of circular parts of the excellent design by Andrew Roth.
This works with flashforge spools I had spare, they have different diameters, and a counterbore when compared to the generic one available from his design.
OD: 200mm
ID: 53mm
CounterBore: 65.5mm with a depth of 6.5mm
Width: 65.5mm
The author remixed this model.
Minor diameter changes to the handle, plates and nut/screw to make it work for flashforge spools.
