Aesthetics in Design
University of Colorado Boulder
Project Duration: 3 weeks
1. Initial Ideation
Internal structure iteration 1 and 2
Final Iteration
2. Manufacturing
a. Gear System - using GearTrax software, I created a rack and pinion gear set.
The software did not come with a gear type that fit my need. To make it work the way I wanted, I copied one of the gears teeth to a new layer. With the tooth, I extruded it 0.125" and then made a plane on the bottom of that extrude. From here, I again used the circular pattern function around the diameter of my water bottle and cleaned up the edges.
Testing gear design
Final 3D print
Printer type - Polyjet
b. Machining
Drilling through first layer of water bottle to rivet in pinions
3. Final Prototype

Exploded view showing how gears were attached.
1. A hole was drilled into the first layer of a dual layer stainless steel water bottle
2. Gear and spacers riveted into place
Press fit base with external sleeve.
