This is a simple, print in place, hinged phone stand. After completing the print, gently work the hinge until it moves freely. I designed the hinge with very tight tolerances to help with stability.
I my opinion, it's best to print this with high infill--80% for more durability in the hinge but lower infill will work but it won't save you much print time or plastic so you might as well go for it with a higher infill.
When folded, the dimension are approximately the same as a US business card, so it travels well. I've enjoyed using this as a way to easily take timed group photos, time lapses, etc. as well as make it easier to watch shows on my phone on an airplane or at the kitchen counter. I hope you like it too!
