Grimdark Checkpoint Gate & Watch Towers – Modular Sci-Fi Wargaming Terrain - Digital Download .STL file for 3D Printing

Defend the perimeter, control access routes, and create imposing battlefield choke points with this modular Grimdark Checkpoint Gate.

This terrain set combines heavily armored gate sections with elevated watch towers, allowing you to create anything from a small security checkpoint to the main entrance of a vast industrial complex, military base, prison, hive district, or fortified settlement.

The modular design allows multiple assembly options, including single- and double-door configurations, as well as open and closed variants to suit different mission objectives and battlefield layouts. The elevated towers provide excellent firing positions and visual focal points, while the industrial architecture fits naturally into grimdark, dystopian, and science-fiction settings.

Designed for home 3D printing, the parts are easy to print and assemble, yet maintain a strong tabletop presence.

Perfect for:

• Grimdark battlefields
• Hive cities
• Industrial complexes
• Military compounds
• Security checkpoints
• Prison facilities
• Colony worlds
• Post-apocalyptic settlements

Compatible with many popular sci-fi miniature games and scaled for 28mm heroic miniatures.

• No supports needed
• Fits on a standard 20x20 cm printer bed
• Easily rescalable for other game scales (e.g., 20mm, 32mm)
• This model includes crisp brick textures, distinct window frames, and realistic roof tiles, ideal for painting and weathering to match your tabletop theme.

The files are set at 28mm (1/56) Scale and can easily be printed on a Creality K1. Furthermore, they can be easily scaled up or down to 1/120 for FDM printers.

114% - 32mm (1/50)
100% - 28mm (1/56)
77,77% - 20mm (1/72)
64% - HO (1/87)
56% - 15mm (1/100)

15mm Scale is compatible with large-scale fantasy and historical battles, such as Warmaster or other small-scale medieval wargames.

20mm Scale is less commonly used for fantasy settings, but can suit model builders or players looking to integrate terrain with historical collections.

28mm Scale is the most popular choice and fits a wide range of games, including Dungeons & Dragons, Frostgrave, Mordheim, Kings of War, and many other skirmish or narrative-driven systems.

32mm Scale works well with slightly larger, more detailed miniatures used in modern fantasy RPGs and board games, such as Cthulhu: Death May Die or Massive Darkness, where a more cinematic table presence is desired.
