I did play with those 3D scanner thingy in an expo
I ask them to scan my whole face and body. Want that instead?
3D scanners aren't precise, these kind of things need very high precision. And the 3D scanner file results are a mess. It would be faster to create high precision model using CAD from scratch altogether.
BTW judging by your cooling mod, you obviously have the skill and tools to do a manual mockup of the Win 1. Perhaps from styrofoam first then went gradually up to resin? I mean 3D printing don't necessarily means 1 trip as well. Trials and errors are needed and they come in much more expensive than manual.
