zerobot bottom shell

i connected the little tower supports on the bottom of the model so they would not fall apart while taking off the supports, and form a more stable structure, there was one small spot on the bottom rear the raised part that had some holes that i was not able to close up, but it should print fine. i also included the sketchup file as a starting point to fix if needed.

I am thinking of adding a hole to be able to screw in the motors rather than mount them with hot glue.

After printing, i am really happy with how it turned out. It was really easy to remove the supports without having to worry about the fragile tower supports.
