So this is a design to adapt to any standard size hotwheels to use it as an car ornament. You will need a M3 screw, an M3 nut and a pc fan ball bearing, I used a W60/2.5ZA bearing. The size of the ball bearing is OD: 8mm ID: 2.8mm Height: 4mm
The base for the hotwheel you can use double sided tape to get the car to stick, and use the M3 screw and just self tap the base to it.
I recommend to print it with ABS or PETG so it resist the summer heat. And make sure to use double sided tape to dashboard so it doesn't fly off.
This is model is inspired with the viral video of this car:
