Sound Cannon!

We at TwistyPhone used Tinkercad to design this project, an sound cannon which greatly amplifies the sound. If you are going to print our sound cannon, do not print as is, you WILL NOT be able to get the supports out from the inside, take the stl. go to Tinkercad or other editing software, ungroup the cannon, NOT the phone holder (other piece) and spread each piece out at ground zero so that they will all print to the best of your knowledge with functionality, then print.
