My version of a top mount filament holder for the Kingroon Kp3s. It balances the spool perfectly over the post while leaving one side open to change spools one handed. Can be rotated to whatever feed angle you want to align better with the extruder. Only the "top cap" needs support. Requires 2 608 skate bearings.
