The Smartphone bracket is from the company Tiakia. I don't know how much they sell of it and thought no one will ever ask for it. But today I watched the princore video and he also had this holder. So I decided to publish these rubbers after all.
This smaprtphone bracket is fine, but the rubbers seem to sit pretty loose and I expected to leave them soon-ish, so I decided to make them myselft first with better fixing.
The red hook at the bottom is not yet published, which also makes no real sense, because the thread twists and therefore the angle is always a different and thus mostly no help (gluing the thread should actually help, but somehow does not).
Made in OpenScad, scad file attached.
