Summary

This is a fire handle nearly identical to one in a Boeing 737 cockpit.
The design is so that it can be put in a panel, and should lift/turn as in the real thing.

Instructions

The print is done in 4 parts.
For the actual handle, there are two parts: one that is the main body and can be made out of any kind of plastic (the real thing is black coloured) and a top piece to be made out of clear plastic - this part can be put on top once lights are in place.
There are two other parts (I've named them "Box").
These go underneath the panel the handles are mounted on, and then allow the handles to be pulled and turned, as in the real thing. However, my design unfortunately only allows them to be turned one way.

My 3D printer died, so I can't attach a picture, but when I do it, it should be accessible at http://cockpitonabudget.wordpress.com
