!!!!!Replacing Larger Brass Extruder Gear
[+The original extruder gear is made from brass and has larger, less sharp teeth to bite into the filament. Jetguy did some test prints and found the I3 gear did not print as well at finer detail than the original Duplicator 4 or Flash Forge gears did. The following page has more information on that test and the gears. +]

'''Instructions:'''
*Laser cut or print. The laser cut parts should have the enclosure holes counter sunk so the original screws can be used. If the part was laser cut in plexiglass then carefully use a larger drill bit with the drill in reverse to make the counter sinks.
*Remove the wiring from the power outlet to the power supply (note where the wires go) and then mount the power socket on the new back plate. Install any 40mm 12VDC fans with the air flowing in towards the controller and connect the fan power to the unused V+ and COM terminals on the DC power supply.
*Reinstall on the back using the original screws.

If you can solder, great, then the best thing long term is place a screw terminal block on the wires making connecting any fan or replacement fan that much easier in the future. Obviously the fan is red and black wires so just match colors.
