This model was design for looks and not function. All the parts were printed separately and glued together. I used a stainless steel peel and stick  for the body and doors. I did do a lot of sanding and smoothing  on the printed parts to get the best results.

I include a STEP file and that is what should be used for slicing.

This is what I used to cover it: https://www.amazon.com/dp/B07QQB3W2G?psc=1&ref=ppx_yo2ov_dt_b_product_details

I updated the STEP file. All the parts are now separate and can be split into parts within Prusa slicer.
