Thrustmaster TPR Pedals Ball Joint Bracket

thingiverse

This is a replacement for the small ball joint attachment bracket on the Thrustmaster TPR pedals. It attaches the airbrake pedals directly to the ball joint on the airbrake sensor. The original part appears to be made from compressed sintered metal, which significantly weakens its strength compared to what it should be. The original bracket also suffers from a critical design flaw where only a thin amount of metal surrounds the thread. When the ball screw is screwed in with the supplied nut for spacing, the screw thread barely reaches as deep as this thin section of the thread before breaking apart. My own bracket failed under these circumstances when the thin metal surrounding the thread snapped. The replacement part has been specifically designed to be significantly stronger than the original, featuring more material surrounding the entire length of the thread. The replacement is also taller, eliminating the need for the spacer nut and allowing a longer section of the ball screw thread to enter the actual bracket. The primary screw hole for the ball screw features an M5 thread. By extending the length of the thread, it becomes unnecessary to use the extra nut that spaces the ball joint from the pedal. To ensure precise printing of the M5 thread, I recommend printing the part so that the ball screw thread is perpendicular to the print bed. The two attachment holes are precisely 3.5mm wide to accommodate the M3 screws. These holes are spaced 20mm apart and remain unthreaded, just like on the original part. Unlike the original part, there is no alignment pin as it can be challenging to print properly and is deemed unnecessary in this design. This replacement bracket may save expensive pedals for someone else as well!
