Lightweight 6-spoke wheel for 1/10 RC Touring Car

thingiverse

I got fed up with snapping plastic wheels around the hub on my 1/10 touring car, specifically the Sunrc Blaze D2 from HobbyKing, mainly when racing on asphalt and concrete parking lots without ever hitting anything. A few sideways were enough to snap those wheels completely. That's why I design my own wheels. I've had good experience printing some other people's designs but they are often heavy and take a long time to print. My design is solely focused on lightweight, quick print times with minimal support required (as short as 37 minutes with PETG), and yet strong enough for concrete track abuse. I think I've achieved most of my goals. The last point remains to be proven through some long-term tests. This project is a work in progress. I print with PETG but I've also done PLA+ with my prototypes, which held up just fine. ABS would likely be stronger, but I try to use PETG as a substitute whenever possible. Here are three versions of different offsets: 0mm, 1mm, and 3mm. Edit: I made a mistake in the 3mm offset version. I removed it and uploaded the correct file (the file name is now ....3mmOffset2.stl). Update November 1st, 2019: Last night, I conducted some rigorous stress testing and had a once-in-a-blue-moon top-speed-wheel-to-wheel encounter. My car rolled and flipped rigorously at least ten times landed on the side of its wheels snapping two of them. Before that, they'd been standing up to high-Gs and side-ways on asphalt parking lots with no problem. Based on these results, I created version 2 with minimal reinforcement (rim wall and spoke/hub joining area). It adds only one gram to each wheel. I was expecting two grams, so I might make an even beefier version in the future depending on how well version 2 performs in tests.
