How I Designed This

This was designed using an existing Brain Gear and a modified gear. It was designed to be printed without support, using 45 degree angles.

Instructions

1. Print 12 P-Brain Gears
2. Print 5 Brain Gear links
3. Print 1 Brain Gear Link to base
4. Print 1 base
5. Assemble carefully using epoxy to bond links
6. Rotate and be amazed. :)

1. Print 12 P-Brain Gears 2. Print 5 Brain Gear links 3. Print 1 Brain Gear Link to base 4. Print 1 base 5. Assemble carefully using epoxy to bond links 6. Rotate and be amazed. :)

Duration:

3 Days

Preparation:

You will need:

• 1 3D printer.
• 2 part Epoxy (JB-Weld works well).

You must start the project by ordering the color/s of filament you wish to use to print with. It is recommended that you use multiple colors for the gears to highlight them spinning.
