I printed the original Flippin' Folding Phone stand by alvinhochun (https://www.thingiverse.com/thing:497035), then I got the inspiration to design a flat folding one. I saw he also has one, but tought the joints could be better, and I added a little piece, that holds it in closed position, when folded.

Dimensions are not like on the ones credited, as I designed from the ground up.

If you want it to look better, you can change the filament colour mid print, to give it a more defined look (like on the pictures).

Hope you like it. Let me know if you want to see any modifications to the design.

Uploaded bottom plate without the graphics for easier and faster printing.
