A few members of our D&D group use iPads for character sheets and spell management, so for my first design of my own creation I made a combination iPad/Tablet stand that includes an integrated dice staging area, a place for your mechanical pencils/pens/erasers, and a little area for the stylus to rest on.
This is the first iteration, but it does seem to fit even jumbo dice comfortably (see attached pictures.) Surprisingly for a first iteration it seems to print and function pretty perfectly. Hope you enjoy!
For reference, I printed this on a Bambu A1, with inland PLA+ filament.
