This is my biggest project to date, with a mix of 3D printed parts, RC components, and standard fasteners. Based on an RC car we had as children in the 1980s, I obtained a rough old version from eBay and designed based on that. The challenge was more difficult than originally thought, and only the original chassis dimensions have remained the same with a 178mm wheel base.
The Mini Stock project has been ongoing for a few months now. It’s finally starting to look more “polished” with good feedback from Makerworld users who have downloaded the files.
All the files for this project are free to download and are collected together here https://makerworld.com/en/collections/6152951-mini-stock-car-designs
Body styles and options are in design and are being frequently updated. The chassis has been in beta release while I sorted out a few issues. The first full release is now (May 2025) being collated and the docuementation updated.
The 2 body styles so far produced have been the biggest challenge of the project so far. The Mini body is reminiscent of the 1980s kit body, whereas the Roadster body is entirely my creation, perhaps in the style of Deuce Coupe.
Having no suspension, these are very simple to build. Any 2ch RC system can be used with cheap drive components. The full build document with all the parts required can be found on Makerworld with the STL files for the chassis https://makerworld.com/en/models/1237561-rc-mini-stock-car-chassis-1-12#profileId-1257524
