https://amosdudley.com/weblog/Designing-PPE-for-Hilde has a story of designing a 3d print for foxtails.

Reminded of the guy who straightened his teeth in 16 weeks for $60 (with access to a university 3D printer):

The blog about the camera is fascinating too, especially the shutter mechanism:

I think this article was mostly a summary of the engineer’s personal blog post: http://amosdudley.com/weblog/SLO-Camera - linked from the post with example photos in another comment.

Video editing, 3D part packing -- anything other off-label uses for Blender?

> We used Blender’s physics engine to pour parts into a virtual volume, then exploited its collision-avoidance behavior to re-sort them into a tight 3D packing optimized for overlapping concavity.

There's a more detailed tutorial on how to use physics to do 3D part packing here:
