Find a position to drill on the car body as close to the back end as possible.

1) Flip the car over on its back.
2) Using the drill press and the larger Forstener bit, Drill a hole slightly deeper than the thickness of the film canister cap.
3) Replace the bit with the smaller bit and drill a second hole, this time drill as deep into the car body as you can without protruding on the other side.
4) With the Dremel tool, sand a notch on one side of the canister so you can get your finger under the cap to remove it.
5) Test fit the canister and lid to the hole.
