Update: April 10, 2023 It's been about three years since the original design, and the button, printed with flexible PLA in the original design has crumbled to tiny pieces. Time for a design re-think! ...so, I've created an updated version that only uses "standard" PLA for the entire thing. I also took the opportunity to... better align the lock button position with the circuit board - it worked fine, but the positioning was a couple of millimetres off clarify the battery orientation indicator in the key fob base (positive side down !) fill the hole for the LED indicator (you don't have to fill anything with glue now) - there's no need for a hole there in the first place, since the PLA in that location is thin and translucent enough that you can easily see the indicator light through it. For this new version, use the following STL files: key-fob-button_10-04-2023.stl key-fob-base_10-04-2023.stl key-fob-lid_10-04-2023.stl ...and just print everything with normal PLA.

Given that the car was almost 15 years old at the time, I wasn't overly surprised, but when I called up about the cost of replacing the fobs I was told they were in the region of A$450. Each. Not wanting to spend close to A$1000 to replace them, I instead bought a cheap 3D printer with the intention of replacing the case (since everything else was fine) with one of my own design. Yes - this problem is the reason I bought a 3D printer. How much did it save me? By my reckoning (ignoring the time spent designing and working out the kinks), about $700 in the clear. Take that, key fob industry! What? There are three parts to the print: the front and
