Digital STL files of an insert for the board game The White Castle Duel (2025) 🏯

Step into a focused head-to-head battle in The White Castle Duel with a custom insert that transforms the box into a calm, structured space, where every component has its place and the table stays dedicated to sharp tactics and perfect timing.

The printed product is available here.

🎨 The player boxes are designed to match each player’s color, making setup easier, speeding up preparation, and clearly defining each player’s space from the very first turn to the last.
🧭 Subtle symbols built directly into each compartment guide component placement naturally, so setup and cleanup become second nature after just one game.
🧩 The layout is crafted to support the rhythm of play, keeping essential components within reach while reducing clutter on the table.
🃏 Fits sleeved and unsleeved cards (up to 80 microns thickness) - protects your cards and keeps gameplay smooth.
