Step 3: Start Cutting
To cut the gear teeth, start by cutting the circular portions only(see image below) then cut along a connecting lines to get the final shape.
If the part doesn't come out easily, don't force it, doing so will only create rough edges. Flip the part over and score along the lines, the part then should basically fall free.
The gear should be able to be placed around the smaller circular piece and rotate freely, this may require some trimming.
