I was rather disappointing to learn that the original box insert for Dominion (of which I own no rights or privileges to the name, or content of the game or associated expansions) was not designed to hold sleeved cards. This set of prints is designed to replace the card organizer with one that holds sleeved cards in an angled configuration.
Currently it is only designed for the base game, but the pieces can be used to support other games too if you're creative. To make a complete base game set, print:
2x "REAR HOLDER, KINGDOM CARDS"
2x "FRONT HOLDER, KINGDOM CARDS"
1x "REAR HOLDER, LAST KINGDOM CARDS"
1x "FRONT HOLDER, VICTORY CARDS"
1x "REAR HOLDER, CURSE CARDS"
1x "MIDDLE HOLDER, MONEY CARDS" (which has the slots for gold and silver)
1x "FRONT HOLDER, COPPER CARDS"
Note that each part took me around 7 hours on 15% infill but high resolution (so they look nice) and to match the picture it'll take you at least a week of constant printing. Totally worth it though!
Grey, Green, and Gold
I actually used a Monoprice Dual Extrusion printer, which is basically a 2X clone. I used Simplify 3D to customize the printing profile for my machine.
