I've been doing some 3D modeling, designing another spotlight.

Here are the few things I learned for this project:

- When modeling shells use all of the existing parts (vitamins) to see how parts fit together. This saves a lot of filament.

- Create rough models for parts I don't have, to see how they would fit

- (more specific to openscad) Use 2d shapes and extrude them

- 2d polygons are flexible, but time consuming to design. It's ok to get started by combining squares and circles
