A card divider for The Binding Of Isaac: Four Souls to keep different card types separate within the game box.
(this wont work as well with other Card/Deck based games as this is slightly taller)
Use speeds of around 45 to 50mm/s
Rotate the model within your slicer so that the main face is printed "on" the print surface for best results.
The model is only 0.6mm thick so should only take around 25 mins to print.
Modeled in standard Autocad for those interested.
