Custom Bear Extruder – BMG Standalone – PINDA2/BLTouch

This is a remixed version of the Bear Extruder 0.7.0-beta (https://www.thingiverse.com/thing:3716110) with the intent to allow the use of a standalone BMG extruder within the frame of the original extruder body.

Compatible with x-carriage and nozzle fan duct from the Bear Extruder 0.7.0-beta linked above.

BLTouch mount based on vertigo235's mount (https://www.prusaprinters.org/prints/6606-bear-extruder-bltouch-mount).

Both versions (PINDA2 and BLTouch) were printed and tested.

Source files included for possible remixes/adjustments.
