Sumo shields for SparkFun RedBot w/Shadow Chassis

Summary These are sumo shields I created for the 2016 Boise Code Camp robotics competition. http://robotics.pjhayward.net/#/events/2016/march-code-camp If you print them upside down, the design is self-supporting. The holes on the front shield allow an HC-SR04 ultrasonic sensor to be mounted in the shield. Print Settings Printer Brand: Printrbot Printer: Simple Black Rafts: No Supports: No Notes: Flip them over. There's a lot of straight lines in this print, so I enabled acceleration limits in Slic3r and increased my maximum print speed. The acceleration limit prevents jarring the print loose, and let me double my usual maximum print speed. Overall, the print completed in about 66% of the time without the acceleration & speed adjustments, and I had fewer failed prints.
