Interchangeable Wood Phone Backers

Cut the shape from the file on a band saw. Drill the camera hole and file/sand. Please note that this is meant to fit an iPhone 4 or 4S.

Depending on your machine(s), you may be able to laser cut or mill this shape. Please test a small section of the wood to determine the feasibility. Leopardwood is naturally oily and may burn slightly in a laser cutter, and thin wood takes care to mill.

Sand the edges until they're smooth. Sand the corners until they're rounded if you weren't able to achieve this on the band saw.

Cut suction cup tape into thin strips that fit horizontally on the back of your piece. I find that 6 strips is the right amount to keep it secure on your phone. Remove the white backing and apply the adhesive side to the wood backer. Remove the clear backing and apply to your phone.

Cut other woods and follow the same steps. They will adhere firmly to your phone but peel off with a moderate pull, leaving no residue behind. You can use them over and over. If the suction cup side gets dirty and loses some adhesion, simply wipe it with a damp cloth.
