It's almost October which means it's almost Open Hardware Month! Mark your calendars and get excited because there's going to be really amazing speakers and perhaps even some sloths during our 12hr membership livestream! How are you celebrating Open Hardware Month?

Designed and rendered a measuring scoop using #build123d and #blender respectively. The user inputs a target volume for the measuring scoop, and then scipy traverses the search space and finds a scoop with the matching volume. There is a lot of potential in this kind of design optimization approach!

Threw together a very quick and dirty editor / 3D model viewer in nicegui for build123d using ocp_vscode and codemirror. Lots of potential as a model configurator too! Video demo:
