The model is resin print only (15mm). Test-printed on an Anycubic Mono SE (0.05mm layer) using basic resin mixed with about 15% tough resin.
The chassis and wheels are separate prints which can be glued together after printing.
I have added supported hollow files, these printed fine on my own printer, I usually go a bit overboard with support. So feel free to use, but no guarantees. Best to create you own supported files, which are best for you own printer and resin. The none supported files are all solid models which you can hollow out yourself if needed.
The window-frame is rather delicate, so breaks easy. I added some thin plastic-sheet to it, like a real window. Looks great and provides extra strength.
