This is the mount required to mount Printrbot's 3mm Geared stepper motor to your 2014 Simple with a right hand mount. Printrbot does not offer a replacement part to mount the 3mm geared motor onto the 2014 Simple. This mount is extended approximately 1/2 inch and the mount for the aluminum extruder is moved up about 5/16th inch to give clearance for the geared motor. Use the mounting plate supplied with the printrbot 3mm geared motor directly on the right side of the aluminum extruder. http://printrbot.com/shop/3mm-geared-stepper-driver-alu/ You may have to reverse the plug if your motor runs in reverse/ This is an exact replacement for the 2014 Printerbot Simple's extruder mounting plate.
