Description

A Modular Terrain Set for Skirmish-Scale Games

This terrain set was created with small-board games in mind. Curved perimeter walls, broken sections, and internal obstacles create arenas that encourage flanking, tactical movement, and contested objectives.

The result is a table that feels dense and dynamic without becoming cluttered. Every piece is designed to contribute to gameplay, not just fill space.

The Prefab Colosseum sits comfortably within our broader terrain STLs collection, and can be mixed with other modular terrain to expand layouts or vary scenarios between games.

Designed for 3D Printing and Tabletop Play

All Prefab Colosseum pieces are designed for reliable home FDM printing, with sensible part sizes and clean geometry throughout.

Key features include:

• Support-free FDM printing
• Magnet-ready wall sections (we suggest 4×1mm magnets)
• Curved perimeter walls and smaller L-shaped sections
• Multiple wall lengths to suit different printer sizes
• Straight wall variants for flexible layouts
• Scaled for 28–40mm miniatures

Everything is broken down into printer-friendly components. There are no oversized, awkward parts — just terrain that’s easy to print, assemble, and get onto the table.

Scatter, Cover, and Board Control

Alongside the larger wall sections, the set includes smaller elements that function as scatter terrain, helping to break up sightlines and create meaningful cover across the board.

These pieces work well on their own, but also pair naturally with other items from our Scatter Terrain STLs range. This makes it easy to add extra detail or adjust table density without redesigning the entire layout.

Tested on the Table

Inspired by fast-paced arena play and refined through months of printing and gaming, the Prefab Colosseum has been tested across multiple systems and scenarios. The focus is always on:

• Clear movement lanes
• Meaningful cover choices
• Tactical positioning
• Easy setup and teardown

Whether you’re running narrative skirmishes or competitive missions, the terrain is designed to support exciting games without slowing things down.

Expanding Your Terrain Collection

The Prefab Colosseum is designed to grow with your collection. It works as a complete arena on its own, but also integrates cleanly with other terrain STL files and modular scenery built at the same scale.

If you want to try the style before committing to a full set, there’s also a selection of free wargaming STL files available, including terrain and scatter pieces that can be mixed into Colosseum layouts.

Related Colosseum Terrain Sets

If you’re looking for a more ornate or atmospheric take on arena-style terrain, the Gothic Colosseum Terrain offers a darker, more imposing alternative. Featuring gothic stonework, ruined walls, and dramatic vertical elements, it’s ideal for narrative-heavy skirmishes and visually striking tables.

The two sets share compatible scale and modular design, making it easy to mix elements from both ranges if you want to blend clean industrial structures with gothic ruins.
