Minimal Galaxy Z Fold 6 desk stand

This is the simplest design I could create for a desktop phone stand for a foldable device. It fits the Z Fold 6 with the default Samsung S-Pen case with a little wiggle room. It holds the phone in landscape and portrait when unfolded, and also holds it in both orientations when folded.

Since it's so tall, it may take up to an hour to print, depending on your setup. This uses under 20 grams of filament, and is about as compact as I could make it without sacrificing stability or strength.  The vertical reinforcement rib (the triangle) is mandatory to keep the bottom from flexing once the weight of the phone goes on it.

If you have a big, fat case, you may want to scale this up by 1-10% depending on your needs.
