Ford Probe Transponder Case

thingiverse

I designed a custom replacement for my broken transponder keyring that securely holds my device in place. The new design fits snugly, ensuring everything stays put. To assemble this DIY solution, start by cutting and grinding the original keyring into smaller pieces. This will provide you with the necessary components to complete the project. When printing your custom keyring, make sure to orient it correctly - print it upright with the opening facing downwards to ensure a secure fit.
