Design

CAD of the table and shelf in SolidWorks. See shelf animation.

Prototyping

I made a rapid prototype of the desk with recycled cardboard 

I made a higher fidelity 1/3 model table with 3D-printed legs...

The legs fit together well

...and a laser-cut legs and table top.

I built a 3D printer for my floor...

...and used it to print add-ons for the desk...

...such as a wacky pencil holder.
