About this 3D model

The plastic part of my car key broke. I cut off all the leftover plastic from the original key and measured the metal part, trying to recreate it in sketchup. Turned out slightly too small, so its scaled up slightly. The key had no chip in it, luckily. Edit: Turns out there was a chip in the key, it was just hidden. New stl and skp adds space for the chip inside the key.
