The first step of building a scale model of a Tesla Roadster 2 was bonding all the 3D printed parts together. I 3D printed all in PLA on my Prusa Mini. Then I used aggressive 60-grit sandpaper to prepare the surface and fast-dry epoxy glue with a hardener to join the parts. I cleaned up the excess glue using isopropyl alcohol (IPA) to prepare the car for the next step.

Critique:
This test's primary purpose was to review the constraints of printing a 3d model that was not meant to be printed. Although this is an extremely high-quality and beautiful model, it needs extra work to be 3d printable. For example, all the windows and lights were printed 1% to 5% smaller than the originally intended size because otherwise don't fit. The parts need a gutter between them, and these ones are exact to the millimeter which is not accurate on physical objects. The same with the wheels and brakes: I drilled the holes to be 1mm wider in order to fit everything together.
