Toyota Key Case - Remote Button

Our Toyota Corolla was supplied with 2 remote control keys. After both broke open - due to faulty (weak) design, we purchased a replacement at horrendous cost - Toyota do not supply the plastic moldings only.
When the replacement broke - I modelled and printed a replacement - there are 2 parts, the Upper case accepts the remote control assembly, the lower case has a hole to fit the key into, then the assembly is held together with 4 CSK XR Screws PZK35X10.
The 3D printed part is far stronger than the original casing.
