Instructions
Both can be installed separately with M3x8mm screws and 20x20 M3 t-nuts. Both stand and sensors can be printed mirrored when you don't like the orientation. Current orientation : meant for standard E3, leaning inward, connected to the extruder by additional bowden tube. ( left side, facing forwards for the bowden setup, right side, facing backwards for the Direct Drive ). In both cases : bowden tube reaches around the side extrusion in order to keep it from getting  into Z lead screw's or X toolhead's way. Compatible with my other models.
