Something I made for my RC cars so the tires don't touch the ground. You can make your own stickers or nameplates to put on the sides. Feel free to remix and custom to your needs.
One is 70 mm tall, another is 50mm tall.
1/10, 18, 1/16 should fit without issues.

Width is 90cm, and lowest point is 120cm, on the lower version, it should even be narrower (I didn't measure, sorry)

Doesn't need support, and even draft quality is good enough if you want to print it. Just orient it properly. I'll try to make sure the stl has the correct orientation when uploading, but do check if your orientation is not where I meant it to be printed at.
