Bondtech BMG Upgrade MK3S FDM printable new sensor integrated

cults3d

This is a remix of the Original Bondtech BMG Upgrade extruder integrated with the new MK3S filament sensor. I made modifications for friendly printing with FDM printers, which include 4 point screws for installing the stepper motor instead of 3 like the original from Bondtech. I included two versions of the sensor's cover to use with PC4-M6 or PC4-M10. The design includes Bear X_carriage modified, and more information can be found at https://github.com/gregsaun/bear_extruder_and_x_axis/tree/master/optional_parts/bondtech_x_carriage.

Mixed from the original extruder design: https://github.com/BondtechAB and for the X carriage from: https://github.com/gregsaun UPDATE 1 05/03/19 ******* I added a version of the extruder body with a square nut instead of the M3 threaded insert. If you choose to print this version, use it in combination with "Hinge with 2 mm recession". Added Step files. UPDATE 2 05/03/19 ******* New sensor cover. Print this version; I previously missed the hole for the screw of sensor, sorry!! UPDATE 3 20/03/19 ******* Corrected the filament path after the sensor (thanks to Gabe Condrea). UPDATE 23/03/19 ****** Made some minor changes on the extruder path and the filament sensor section. Added file lever.stl instead of downloading from my .step file. UPDATE 14/04/19 ****** Removed the fourth hole screw because it was unusable without special screws. UPDATE 16/05/19 ****** Added "Square method" in some parts where holes are printed in vertical without support (thanks to "curt_darius").
