Rostock Max V2 extruder motor mount for use with Flex3drive

This fits the NEMA 17 extruder motor and the bell housing from the Flex3drive extruder. The motor is mounted to one of the motor bracket points on the top of the printer, and it puts the driveshaft in an orientation to curve down to the effector without interference.

I am not the inventor of this extruder, I merely bought one and am very happy with it!
