This is a camper that fits in the rear bed of the Tamiya RC Toyota Hilux High Lift. This fits over the top of the stock light rack. I left out the windows as I thought it'd be better to cut out clear plastic so you could see into the camper and make an interior. You could easily just print black panels to fit the window openings.
I had to split this up into multiple panels so I could print it on my Prusa Mini so it will need to be glued together after printing.
I recommend PETG or some other tough filament that will hold up to the rigors of RC trail running.
