This is a derivative of the excellent Aptera model by dtiemeyer. Original model - https://www.thingiverse.com/thing:5242564/makes

This version is better suited for printing via FDM at a smaller scale than the original. The changes I've made from the original was to remove the solar panel detail and thicken the walls of the wheel pants. I've printed as small as 1:64 Hot Wheels scale.

Cura will tell you that the model is not watertight but it should still print as-is. Best to print on the tail edge as originally oriented but you should use a raft and supports given the small tail-end footprint. When printing at 1:64 scale I had the most success using Standard resolution of 0.2mm.
