WOBBLE

The purpose of this project is to demonstrate how to construct moving yard art.

Johnson, my partner, and I based our project off of the British/Iraqi Architect Zaha Hadid. She uses curved shapes like ones in the picture below that push modern architecture to its limits.

Materials and Tools:

• A 3D printer
• 3D modeling software
• Low speed mid torque motor (200:1)
• Battery box (3V)
• Alligator clips
• Wooden Dowels
• Drill/Drill press
• Wood for spinning piece

Steps:

The first thing we did was to design a one-way universal axle. This was not hard, but we went through 2 different iterations; the first was a proof of concept and seccond for accommodating the wooden dowel.

After our first 3D printed design, the 3D printers died and stopped cooperating. So, we spent a good week or so tinkering, troubleshooting, and finally fixing the printers. The problem we found was the live adjust z was off by a few tenths of a millimetre, and the printer needed to be calibrated.

After the issues with the 3D printers were fixed, we finished the final 3D design, and printed it. In total, it took 15 hours to print.

The only issue that arose from the 3D printer, was the x-axis slipped causing upper layers to print further left than the base.

Finally, after printing and fixing the visible imperfections with a heat gun, we attached the motor to its holder and cut the dowels to a desirable length, and finally, made and attached a plane.

The plane was was made from a tree that fell down outside. We decided to make a plane to showcase the swooping and diving motions from the rotation of the dowel. Overall, the project ended up working with the exception of the plane; it was too heavy for the motor to rotate.
