Ender 3 S1 and S1 Pro 90 degree top mount arm for Sunlu S2 tray

90 degree top mount arm for Ender 3 S1 (Pro) with holes spaced for Djngnear's Sunlu S2 filament dryer tray.  While not required, I also recommend using the Sunlu S2 reverse bowden adapter by Martin_au to complete the setup.

All holes are sized to accept M3 heat-set inserts.  This allows the attachment of the runout sensor to either side of the arm and attachment of the S2 tray to the arm using M3 bolts.

I've included the stl and f3d to allow easier remixing since this arm could be used to mount any number of things.

The arm itself is a heavily modified version of this build off thingiverse.
