I designed this to fit the contour of the steering column as the boost controller on my car was stuck on with thick sticky pads but it wouldnt stay no matter what I did. It was a combination of the angle the pads touched the plastic and the dashboard cleaner I used on the car so I decided it was sensible to design something that is a better shape for the job.I printed it in Polycarbonate, would have been a better finish in ASA but i'm not that bothered, I just wanted functionality in this case. As you can see it works perfectly for what I intended!Print it with the rear flat on the deck with support so it prints the GTR logo.
