This is a E3D Buggy model updated with a Back to the Future Delorean Time Machine. No supports are required and you can use minimal infill (10% is fine).
This was made from a couple of different things. First is the Delorean polly model by Totus3DMaker (https://www.thingiverse.com/thing:4416569/files). The second model is the E3D Buggy model.
Updated 11/18/22: Added Version 2 to include the Flux Capacitor to model.
Enjoy!
The author remixed this model.
