Outcome

"headrush" is a prototype of a final holder project for the fabrication course at Carnegie Mellon's IDeATe program, digiTOOL. This project combines the skills I have learned in the CAD program, AutoDesk Fusion 360, and in digital fabrication machines - laser cutters and 3D printers. 

Problem:

I am a very organized person and like to keep things clean. The coffee table in the living room of my apartment has no dividers or anything, so throughout the day, various keys, wallets, glasses, and other accessories get piled on top of each other on the table, creating a lot of disorganization and discomfort for me.

This is especially prevalent during nights where I host with friends. All the drinks, shot glasses, Dixie cups, etc. would be all over the coffee table which pains me every time I wake up the next morning and walk to the living room.

Sketch:

One way to solve this issue is to fabricate a piece that can hold multiple shot glasses. I intend to make this model movable since the configuration of the way people sit is not constant. 

The overall curvature of this piece is to complement the bird's eye shape of the shot glasses and bottles. Some objective precedents I looked at were the shape of the boomerang and the fidget spinner.

Digital Modelling:

The first step to actually making this piece is to use a CAD program to model this. I used a series of spline and circle commands in the sketch component and a series of extrusions using AutoDesk Fusion 360. The joint part (the elbow) of the model is a piece in which I would 3D-print; however, I will also 3D-print a cylindrical joint half the height so that another shot glass can potentially go into that hole.

Technical Axonometric:

Most of the holes have a radius of 0.75 in., which is the midpoint of my shot glasses. The glass would be able to sit on it, similar to the cup holders in movie theaters. 

Technical Assembled Axonometric:

Because the overall plan for this is to be able to rotate, only a certain number of pieces can be glued together, which enhances the necessity of a middle joint in the "elbow" area of the model.

Plan Series:

Because the position and location where people sit are different every time, I allowed the model to be movable in a rotating axis. Therefore, after studying all the positions where people can sit, I am able to show that this prototype can work for all sedentary configurations.

Fabrication:

I used a rabbit laser cutter to cut through a 1/4" plywood. One 30x30" piece of plywood is sufficient for all the pieces to cut.

Assembly:

I used wood glue to glue the necessary parts together. All of it cannot be assembled with wood glue, as all of them need to be rotated.

Challenge:

Unfortunately, all of the 3D-printers were down. So the joint I was planning on printing was not going to happen. I instead used a clamp to hold all the pieces together.
