The Orange Screamer - A wide-area annoyance device Keychain with Solidworks 2014 source.

Decided to make this into a key chain from the original work by AndyGadget at http://www.thingiverse.com/thing:455093 I used the stls not found in his zip for this.
If you work with the source you can remove the key chain hole towards the end of the source tree.

**There is a Snap Fit version of this now** http://www.thingiverse.com/thing:482840
