In the picture you see the stand alone, and the stand with the car on it. In my case this is a Maisto 82351 Aston Martin Red Bull Racing RB15 as RC model (yea, I could drive these).
It's made in FreeCad 0.20.2, you should be able to customize height/size there. File is incuded.
This is NOT a remix, but I want to give credit for the idea to present the models in an angled manner to https://www.printables.com/de/model/424770-model-car-angled-stand. Thanks.
The author marked this model as their own original creation.
