ARRMA 3S TBONE BUMPER HINGE PIN PLATE FIX

thingiverse

This was designed to fix a Tbone bumper design flaw affecting their front bumpers for 3s typhon and similar models. It can be used on Arrma's 3s line and 4s line if necessary. Tbone front bumpers have a known design issue with the block holding the hinge pin plate, causing it to break easily and often resulting in the loss of the hinge pin plate. Tbone has acknowledged this problem and promised multiple times that they would release an updated version. Instead, they offered a solution consisting of a short piece of aluminum angle with a pre-drilled hole. However, this solution only created additional problems, prompting me to take matters into my own hands and create this hinge pin retainer for the Arrma community. The installation process is straightforward: simply attach the part and use the factory-supplied screws for the original front bumper. To install the Tbone bumper, attach it as normal with two screws and a spacer on the bottom of the chassis. This solution is simple, effective, and should have been implemented from the start. Feel free to print this design in any material you prefer, using supports if necessary.
