I need cad files for my invention

From what you've told me (privately), I've understood that you're supposed to design a remote-controlled car that has a selfie stick attached to it...

Did you even start? or you're expecting us to design it for you?
If you've begun designing and want help, post the CAD files and the issue you're facing.
If you want sb. to design it for you, post here to hire a designer (Paid work):

But if you're like 90% of those who have similar requests and want it designed for you for free, please share with us who designed it for you so that we could thank him properly for his pure kindness...
