IR Filament Sensor Adapted for Bondtech Prusa Mk2/s upgrade

I didn't like the design of the Bondtech IR filament sensor adapter for the Mk2/s upgrade extruder (https://github.com/BondtechAB/Bondtech_Prusa_i3/tree/master/CAD-Files/MK3s%20Sensor%20Add-On), so I made my own. this one flips the lever arm around 180 deg so the hinge point is at the back, adds a screw-down cap (instead of a snap-in), and gives the option for a bowden tube connector (PC4-M10x1.0) for use with the MMU2 or a reverse bowden set-up. The filament inlet has a 60 deg. internal chamfer to aid in loading, or to locate the end of a bowden tube (i.e. reverse bowden or MMU2 set up). It also includes a filler for the laser sensor slot so that the filament path is better constrained between the new sensor and the bondtech gears. Category: 3D Printer Extruders
