Underwater Cities + expansion storage

thingiverse

This expansion fits perfectly with Underwater Cities and Discoveries, specifically the Rio Grande edition, along with sleeved cards. The only component removed from the base game is the original player board, as the expansion offers three-layer boards. The box lid may be slightly elevated by 1-2 mm due to reduced thickness. The card tray measures 314 mm in length and exceeds standard print bed size, so it's best printed at a 45-degree angle for optimal fit. Additionally, I've included a sliced card tray design, cut into two parts, but have yet to test or print it.
