THESE DIRECTIONS HAVE BEEN UPDATED!!!!! DUE TO AN UNDERPOWERED MOTOR, THE ARMS HAVE BEEN REDESIGNED!!

Also, put grease on the gears and in their sockets.

You also need about a foot of wire for the positive and negative contacts to reach the momentary push button.

Motor Parts (the wiring directions are in the last image)

If the motor seems underpowered, just add another battery pack and connect it to the contacts like the first battery pack (shown in the images above).

(Place the motor in this case so that the wires pass through the slot and solder one end to an end of the battery pack and the other end to the momentary push switch as shown in the last image. Also, in order to center the shims, motor shaft, motor case, and motor arm there are indicator slots on the sides of each so that you can line them up properly.)

3D PRINTING SETTINGS
.2-.3mm for larger pieces, gearbox halves, chain teeth (all the same size no big or small ones anymore), 1/2in pegs, saw tooth spacer, motor (case holder, mount arm, shims, and trigger holder)

.1mm-.2mm for gears

You can keep the saw teeth flat on the build plate or orient the saw teeth 45 degrees on their sides so that the male and female portions of the teeth stay circular and don't warp and become oval. (Printing them flat works for me though.)

.3mm for larger pieces, chain teeth, saw tooth spacer, motor(case holder, mount arm, shims, and trigger holder

Print Sect. 4 flat with the gear mount area facing up.

.1mm for all pegs
