Iron Helm insert (fits Iron Helper add-on)
thingiverse
The Iron Chest just barely closes flush with the Iron Helper cards and trackers on top of this insert, IF you keep the Iron Helper standees separate from their stands AND you have the newer red halmas from the base game. If you have the the bigger wood-colored ones, you *might* get them to fit but I can't guarantee it. The only reason mine fit is because one of the 3D-printed minis from the Game Crafter came broken, so I just tossed that one from my copy.
