Update 9/8/14:
I added a new smooth running seahorse gear version (v3). The new version does not latch into a closed position and is suitable to drive
with a motor, etc.
To clarify, choose the version of the gear based on desired action.
Gear v2 - Latching
Gear v3 - Smooth running
Enjoy!
Update 6/9/14:
Added DXF files, so hopefully people with laser cutters can try this out too.
Update: 2/27/14:
New Version (2.1) of the arm. I replaced the pins with simple holes. Use raw 1.75mm filament for the pins/rivets, using the methods described here for using rivets as hinges. Look at the section titled 'USING FILAMENT TO MAKE SOLID RIVETS AND HINGES' towards the end of the article :

I used a lighter instead of a heat gun. It's quite easy and much stronger than a printed pin.
Update 2/26/14:
New Version with stronger pins.... is a failure. Pins do not mate properly. I have a new vetted design with a simpler pin made from a raw filament 'rivet'. I'll post updated files and instructions on 2/27/14
Update 2/26/14: New Version with (hopefully) stronger pins.
Units are now in Metric.
