Simple Adjustable Tablet Stand

I created this tablet stand because I was having trouble calibrating my printer after a filament change, and every attempt to print a print-in-place adjustable tablet stand failed. The moving parts just kept fusing together.
Instead of persevering and fixing the inherent tolerance issue, I just made a tablet stand where the parts are separate and really difficult to mess up. Tolerances be damned!

Anyway, print 2 copies of the Arm and one of the Stand. Insert the square-shaped pegs of the Stand into the appropriate square-shaped holes of the Arms to set your desired tilt level.
The tilt angles weren't chosen with accuracy or thoughtfulness; they're kinda just whatever happened to work out, but it does what I need it to.
