This is really not as polished as I'd like but I've been meaning to upload it so here it is. The 100 card version has an openscad file that can be used to emboss text but it sounds like that's going to be a prusaslicer feature soon.

The hinge between the two pieces is a piece of spare 1.75mm filament.

Might need to reorient the 3mf/STLs for printing.

Warning, these are not sized for sideboards, they fit the advertised number of cards in dragon shields (I think) and not much more.

Shoutout to MGN who helped/carried me thorough the initial design of this.
