Eiganjo Castle Commander Deck Box

A support-free deck box for 100 sleeved Commander-sized cards, topped by an original Japanese castle inspired by Eiganjo. The printed example uses a white body, dark-blue lid, turquoise roofs and speckled white walls. The castle lifts off the lid, so each part prints flat in its strongest orientation.

The cavity is 67 × 94 × 66.5 mm. The complete box is about 103 × 76 × 130 mm, including the castle. No magnets, screws or glue are required.

Please carry a full box by its body. The four printed snaps hold the lid securely during normal handling, but they are not a carrying latch. A full 100-card deck is heavy enough that lifting the whole box by the lid or castle can allow the body and cards to drop.

What you print

• eiganjo_body.stl — the card tray, printed open side up.

• eiganjo_body_coupon.stl — a quick top-section coupon for checking the lid fit before printing the full body.

• eiganjo_lid.stl — the snap-fit slab and castle locating rib, printed flange down.

• eiganjo_castle_2c.stl — recommended two-colour castle.

• eiganjo_castle.stl — single-colour alternative.

• eiganjo_box.scad — parametric source for changing the deck cavity or fit.

Two-colour castle

Import eiganjo_castle_2c.stl into Bambu Studio, right-click it and choose Split → To Parts. It becomes five coordinate-locked parts: one castle_walls shell plus four castle_dark groups for the plinth, stairs and roofs. Assign the walls a light stone colour and all four dark groups one roof colour. Do not move the parts after splitting.

The body and lid may use either matching or contrasting colours. Only the castle wall/roof separation needs to remain consistent for the architecture to read clearly.

Print settings

• PLA, 0.4 mm nozzle, 0.20 mm layers.

• 3 walls and 15% infill.

• No supports on any part.

• Print every STL exactly as exported, flat bottom on the bed.

• Ironing off, especially on the two-colour castle.

• Print the lid together with eiganjo_body_coupon.stl first. Confirm the snap before committing to the full body.

Approximate sliced filament at these settings: body 37 g, lid 33 g, castle 95 g and fit coupon 5 g. A two-colour castle can add about 50 g of purge at default AMS settings; Flush into objects' infill lets the plinth absorb much of it.

Assembly and use

1. Load cards on edge in the body. Their tops finish about 4 mm below the rim.

2. Lower the lid flange into the mouth and press until the four bumps click into the internal grooves.

3. Lower the castle over the rectangular rib on the lid. Its groove has 0.15 mm clearance per side and lifts off without tools.

4. To open the box, put fingers beneath the lid slab's overhanging lip and pull gently. Do not pull on the castle keep.

The castle is deliberately removable. A small bead of glue in its underside groove can make it permanent, but glue is not needed for normal shelf and table use.

Fit tuning

The included coupon reproduces the body's top 10 mm. A good fit seats flat, clicks with light pressure and releases with a deliberate tug on the slab lip. If the flange will not enter, increase fit_clr from 0.15 to 0.20 mm in the OpenSCAD source. If the lid does not click, increase snap_out from 0.40 to 0.50 mm and groove_dp from 0.50 to 0.60 mm, then rebuild.
