This design started from a sketch from a user in the r/pens Discord server who wanted it to be a pen stand. It ended up being a better phone stand, but it can really be used for anything. I've included the Fusion360 file so you can edit it to better suit your needs.
I printed it at .2mm layer height and 20% infill and minimal supports just under the hinges and the overhangs. The tolerances are fairly big, so all printers should be able to easily print this. The holes for the hinges are perfectly sized to slide a piece of 1.75mm filament through.
