This is a chassis for a 3 wheeled robot car. it uses 2 of those geared wheels you can get off of eBay and one front or real swivel wheel. Depending on whether you use front or real wheel drive.
I made it because after some searching on Thingiverse I couldn't find a simple chassis for a 3 wheel robot car.
It's got a section for mounting a couple of small breadboards side by side. I also tried to add some struts to cut down the printing time. I'm not sure if they'll weaken the structure too much. We'll see.
I created this to replace a chassis I bought from eBay that cracked in half when I was messing with it. While I was re-designing it I modded it so it could hold the two small bread boards with an esp8266-12 breakout board as the controller.
I added photos of the parts it's designed to accommodate.I'll add photos of the complete chassis when it's done printing.
