My extruder motor mount just fell apart so I had to print another

I used a ReplicatorG to generate the x3g file for an old makerbot
replicator.
M2 Extruder Motor Mount _Metal

These two drawings are metal mounting for the M2 extruder motor. The
original plastic extruder motor mount got broken and I had a hard time
to make a new one that can square up the motor.
Alternate Extruder Motor Mount for M2

This one can be made out of metal (milled) or printed. It holds the
motor square event if it is made of plastic and the motor gets warm.
You might want to use a pair of Heat Set Inserts for securing the top
bridge member if using plastic or use self tapping screws.
