Step 3: Start Cutting

For cutting the pattern, it is best to start in the middle of a given part. This is because if you cut the part out before removing the details, the pattern will need to be taped to the part. This can leave unwanted tape marks and the patter might not be in exactly the same place.

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.
