HPI RS4 47T Spur Gear (HPI 76817)
thingiverse
This is a custom replacement spur gear for the HPI RS4 Evo3+, its part number being 47T (HPI 76817). It may also fit other RS4 models. Unfortunately, I couldn't find any online retailers that sell this component, so I decided to print it myself using PLA with an infill of 80%. I will update this description after testing its performance. You can view or download the Fusion 360 project here: https://a360.co/2TVXX2G. **Edits** The diameter of the studs was slightly too large, requiring me to melt them to fit the car. I plan to modify it for a better fit soon. After printing with PLA, the gear performed well, but unfortunately, it melted my clutch shoes. However, the gear itself still looks brand new and held up surprisingly well despite taking some punishment.
