This is a pocket watch housing for the highly programmable Makerbot Watch. ( http://wiki.makerbot.com/makerbot-watch ) Designed to protect the circuit board when not in use, while being able to hinge open for easy tinkering.

Inspired by the feedstock hinge ( http://www.thingiverse.com/thing:1358 ) , I tried to use the least amount of hardware as possible. The ABS filament acts as the hinge pin, and the clamshell parts have built-in bumpers that keep all the components well constrained. Adding 3mm magnets will really give the whole thing a robust feel.

There are two versions posted:

1. watch top.stl, watch bottom.stl; -These are pictured and have a more finished looking aesthetic, and more refined bumpers. 2. (rev4).stl; -These are an ultra light weight ribbed version that have a consistent material thickness, however requires a well tuned 3d printer.

For anyone who wants to make something similar, there is a dxf quantifying(1:1) the critical features of the parts.

1. Print STLs
2. Insert circuit board
3. Clean up holes on both parts and insert filament
4. Cut filament "pin" to length, and unleash the creativity

Magnets and acrylic faceplate optional
