I had a misfortune to buy this very poorly made tracked chassis.
I now have some Arduino-based controller to attach to it. I see three posts with what seems to be holes for screws, and two of them even appear level :). Nothig I find on the internet matches the layout. In fact, there is no documentation on that chassis that would describe the layout.
Is there some generic part I could customize to cover this situation? Any tips and tricks for attaching PCBs to chassis would be appreciated.
