My dream muscle car that I do not have, so I modeled it in Modo for 3D printing.
Full model added plus a customizable one for different materials/colors if so preferred.
Printer:
CreatBot DE Plus 3
Rafts:
Doesn't Matter
Resolution:
0.04 - 0.16
Infill:
5% - 100%
Notes:
Note: Model length is 200mm. It can't be scaled down further as the smaller parts will not print no matter how small is your printer nozzle and res. setting.
Also, joints should be used as placeholder to fit the parts into the body, so I recommend using glue, except for fitting the wheels into the tires for which I used a mallet.
Body: manual support added in S3D. Infill 5% and 25% before top surface using S3D variable tool.
Metal parts: Res. 0.04, infill 100%, as small parts will be hard to print. Also, manual support added only under the bumpers joints. Print speed 30mm/s.
Tires and wheels as preferred, but note that front tires are smaller than back tires.
There is a sufficient clearance between the body and parts to fit in, if you have an issue with that, use fine sand paper to sand the edges of the parts. Don't force them in.
Turn the engine on and enjoy the ride :)
I used acrylic paint to tint the windows blue plus the side signal lights before adding two layers of XTC-3D polish.
