This is a model for an existing key. The spare key that I had fits perfectly, but I can change the hole size if your's dont fit. The dimensions are 18,6mm x 59,6mm x 9mm. I can change the dimensions as well . I can change the design, make it for another brand if you wish. With %100 infill density, it is sturdy enough, it doesn't feel cheap. With a decent paintjob, it will look very nice. I can add an addition for a keychain, I didn't add it because I don't like using one.
