Very interesting. Thanks! I wonder if it could be used as an axis in a 3d printer

Not a big fan of Bezos though.

Yeah, I think I see what you mean. I’m very plastic conservative so I hope I can go without printing a second one, therefore the clip idea. Also the clip is a bit more practical better looking.

They fall out. For now I use a rubber band around the case but I don’t like that solution too much. The initial idea was to put a rubber band around the “waist” so that they would be held there. Unfortunately the rubber then doesn’t touch the dart. My current idea for a fix is to make a clip that pushes against that darts sideways through the holes.

This is fantastic! I have half assed plans of a similar design in FreeCAD lying around. I haven’t come around building it yet. I’ll surely take some inspiration here.

Great project! I would love to see them on someone. I fortunately don’t need glasses but I might at some point consider printing sunglasses.

Damn, it took me a while to get this joke. Well done! :D

Yup. It’s not as loud and less energy intensive usually.

Hah, I didn’t mention the most important part. It basically switches on a ventilator when the absolute moisture content outside is lower than inside. This results in drying of the room that you ventilate like a basement with moisture issues. The dew-point acts as a proxy for measuring absolute moisture content.
