thingiverse

Parts needed to launch the ETV (Egg Transport Vehicle) for the Scrambler 2015 division C Science Olympiad are as follows. The design should be fully rule compliant, so please check dimensions before using it. The 2016 redesign of the Launcher Backpack was created to make it easier to launch the cart using a large overhead pulley. This new topper for the launcher is called the Football Launcher, which resembles goal post. I also designed a smaller version of the backpack to save print time and plastic. Note: At the time of upload, this design has not been tested in competition, so its performance is unguaranteed. Instructions: 1.
