My customization project is taking far too long to complete, so while the body work is being done, I've been working on the details. One project I'm re-doing is the 3D printed instrument Speedometer/Tachometer "bucket". The first one fit, but not perfectly and required a mount that was less than satisfactory. My latest version can be found here:

I hope this can help anyone who's original vacuum formed part is no longer usable.
