I've used this project to experiment with Fusion 360. On the whole it has been good, although I did run into a number of features I'm used to on other pro CAD packages that are missing. It seems more of a in development tool, where features are added at the request of engineers in desperation upon finding a tool missing!

Each layer of plywood is a separate 'sketch', that I export to DXF for laser-cutting. The official RPi screen and RPi are a assembly from this guy: https://grabcad.com/library/raspberry-pi-7-display-1

I've opted for the official screen despite being twice the price due to the flex cable connection allowing for a nice tight assembly. Having arrived I'm glad I paid the extra for what is a well engineered bit of kit. The stepped design is to minimise material usage but also aims to pay homage to an old terminal casing dropping around the CRT.
