I know that the controller is glued on the scooter, I know that this contact helps thermal dissipation, but when the joyor starts aging, water starts entering in the body and the glue looses it's strenght. Given that, I decided to lock the controller on a "TPU pillow" so that it doesn't suffers from shocks and doesn't move.

The photo is my prototype, I had to shave some parts on it. The provided stl and fusion 360 doésn't need tuning like that, just print and go. No support needed. Enjoy your scooter.
