I needed an iPad Mini 6 stand that would work with a Spigen Ultra Hybrid Pro case, and also wanted it to have enough of an angle to where I could use the iPad on my desk. This one prints with no supports and holds the iPad firmly in place. It will also hold an iPad Mini without the case, but it is not a snug fit.  It is pretty lightweight and would easily fit inside a backpack or bag.

Printed with an Ultimaker 2+ with a .6 nozzle and .2mm layer height. No supports needed.
