hpi trophy buggy / truggy & vorza hub

thingiverse

I broke too many rear hubs on my trophy truggy, so I decided to create some replacements to print. The hubs were made from PLA, a material that I thought would be fragile but turned out to be surprisingly strong. I was driving over rough terrain and the new hubs performed well, withstanding the impact without any issues. It wasn't until I attempted a high jump that one of them finally broke, requiring me to reach a height of around 1.5 to 2 meters. While an original part would undoubtedly be stronger, if you find yourself in a situation where your hub has broken and you don't have a spare, these printable hubs are definitely worth considering. The printed hubs fit perfectly into my car, with the bearings fitting snugly into place.
