Summary This is a great improvement over my first design. Put a picture of all the versions on here because I think its important to emphasize rapid iteration. The first one took me about 5 minutes to design and 15 minutest to print out. I would try it, figure out an improvement and try again. I think I nailed it on version 4. Overall, I spent about an hour printing and maybe 25 minutes designing. And for anyone who wants to know what that button is... I'm lazy and got tired of awkwardly reaching behind my bot, so I moved a power button up to the front.
