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
