The OpenRC F1 Build Guide

This is the build guide for the OpenR/C Formula 1 car. It´s the third generation 3D printed OpenR/C car and this time around focus is on simplicity! You can print everything in PLA except the tires which are done in in a soft TPE such as NinjaFlex! Of course you can print it in any material you like but for those that want to print a car but only have PLA at hand, this is the project for you!

This guide explains how to assemble the OpenRC F1 car. If you want to add electronics to make it radiocontrolled another step will be added later. If you have questions have a look at the OpenRC Q&A. You can add a question if it haven´t been asked before.

All files needed including STL´s, BOMlist, drawings, STEP file of the assembly are available here:

There are lists and kits for hardware/electronics available here.

There´s a article on Pinshape.com about the OpenRC F1 and if you are unfamiliar with The OpenRC Project you can read this article on Hackaday.com

When you have completed a OpenR/C project you can add it to the OpenRC Buildmap.
