Summary

The stands are comprised of two elements, the main holding elements, and connecting elements. They feel very solid, I recommend putting rubber/double sided tape, something that you can use to increase adhesion both so the phone/tablet doesn't slide, and so the stand doesn't move on the surface you're putting it on.

All of my designs have roughly a 0.1 to 0.3 mm offset/compensation for things to fit together according to how my printer prints. I have no idea if this is a universal problem or not.

Supports on my designs are always minimal if not nonexistent. Here there is none needed.
