Horizon Grid MK.V Terrain: Build Sci-Fi Battlefields

Quick answer

Assemble the Horizon Grid MK.V laser-cut MDF kit in about an hour, then paint and detail it to create a durable, immersive 28mm sci-fi battlefield building.

Assembly steps

1. Dry-fit all pieces: Lay out every laser-cut part on a flat surface. Match tabs to slots without glue first to confirm alignment and identify left/right wall panels. If a tab feels too tight, sand the edge lightly; never force MDF or it may splinter.
2. Glue the wall box: Apply wood glue to the tab joints of the four walls. Press together and check squareness with a carpenter's square. Wipe excess glue with a damp cloth. Let the glue set for at least 15 minutes before moving to the roof.
3. Assemble the functioning doors: Insert the door pins into the pre-cut hinge holes. Test swing before gluing the door frame in place. The doors should open and close freely. If the door binds, sand the hinge slot slightly; do not glue the door itself—only the frame.
4. Attach the roof: Apply glue to the top edges of the walls and set the roof panel in place. Press evenly and hold for 30 seconds. The roof is removable if you leave it unglued, allowing interior access during gameplay.
5. Prime and paint: Spray or brush on a thin coat of acrylic primer. Once dry, paint the building in your chosen sci-fi scheme. Drybrush edges for a worn metallic look. Seal with matte varnish to protect the paint from handling and dice rolls.
