Golden Ratio Seahorse Gears

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.

Print two identical gears and one Left & Right side arm.

For a nice texture use 'Hilbert Curve' for the first and last layer of the seahorse gears.

The 'assembled' file is not set up to print in place. It is for visual reference only.
