Robot Smart-Car Chassis

thingiverse

This is a base for a 3-wheeled robot car. It utilizes two geared wheels you can get off eBay and one front or rear swivel wheel, depending on whether you choose front-wheel drive or all-wheel drive. I built this because after some searching on Thingiverse, I couldn't find a simple base for a three-wheeled robot car. It has a section for mounting a couple of small breadboards side by side. I also tried to add some struts to minimize the printing time. I'm not sure if they'll weaken the structure too much; we'll see how it turns out. I designed this to replace a base I bought from eBay that cracked in half when I was experimenting with it. While I was re-designing it, I modified it so it could hold two small breadboards with an ESP8266-12 breakout board as the controller. I've added photos of the parts it's intended to accommodate. I'll add photos of the complete base when it's finished printing.
