As a part of my senior design project, I did a majority of the 3D modeling and assembly of components. For this project, we used PTC Onshape. Onshape is made by PTC, which also developed CREO. The main driver behind this choice was the ease of editing on the cloud as a team. Some components such as the combustion chamber and loader were entirely designed by the leads of their respective subsystems, so I was in charge of the assembly and modeling of additional components the team forgot such as baseplates and electronics.

I bought some gravity water dispensers for really cheap, and I wanted to convert one of them to be a food dispenser. However, it had very little clearance for food to flow through from. To fix this, I pulled up Fusion 360 and, after some iterations, I decided on a design that would take minimal filament to 3d print, and also handle the weight of a full cat food container. I used Fusion 360's Simulation mode to apply pressures and constraints to see if the print would structurally hold up, printed it, and installed it. Now Gilly can enjoy his food at his leisure, and automates one extra thing.
