Remix of the Heavy Duty Side Spool Arm, specifically for the P1S. Thanks to suit for the original model.
This version can be printed support free and is pretensioned to wrap nicely around the side panel. The structure of the model prevents sagging.
Intentionally the spool will not be completely parallel to the side panel, but with a slight angle towards the back of the printer to support the filament path towards the back.
Best printed almost solid.
As for screws: use 8xM3 or 12xM3 countered by a nut for best strength for mounting the original spoolarm to the model.
The author remixed this model.
Original model makes use of a screwin on the side. That requires to drill a hole into the sidepanel of a P1S. Therefore I remixed the original model to give it more holding strength and also allows for support-free printing. Still uses the great concept of utilizing the original spool arm.
