Injection-moulded from ABS plastic — the same family of materials used in LEGO bricks. ABS does not warp, holds its shape over time, and bonds reliably with superglue (cyanoacrylate) and two-part epoxy. The textured top surface grips PVA, texture paste, and basing sand without needing to score or rough up the surface first. Takes all spray and brush-on primers cleanly.

Every mould in the OBS range is designed in-house using industry-standard CAD — these are not generic imports. We control the full production chain from design through to quality control. Mould lines are clean and consistent.

The hexagonal shape is precision-moulded with clean, straight edges — critical for hex bases that need to sit on hex-grid maps and tile alongside other hexes. At 4mm total height with a substantial bevelled edge, these bases feel solid and stable. The 28mm flat top surface gives enough room for 'Mech models and scenic basing work.

30mm hex is the standard base for BattleTech 'Mechs and other hex-grid wargames. The hexagonal footprint matches hex-map terrain tiles — your base sits in the hex, oriented correctly, with clean edges aligned to the grid. Also used for any tabletop game or RPG that uses hex-based movement.

The 30mm flat-to-flat dimension fits standard BattleTech hex maps. At 35mm point-to-point, the base extends slightly beyond the 30mm measurement at the corners — standard for hex geometry.

One Ecosystem · Every Size · Every Shape

OBS is a modular basing ecosystem designed as a whole — not a random collection of bestsellers. Every size, shape, converter, and tray is planned to work together. Independent and gamer-built.

New products added regularly — the OBS range is always growing.

When gluing a model to a hex base, consider which hex edge faces forward on the map. Most players orient a flat edge toward the front of the 'Mech. Decide before gluing — once the model is set, the facing is permanent.

Wash before priming — a quick rinse in warm soapy water removes mould release residue. Let them dry fully before spraying.

BattleTech bases look great with simple terrain — rubble, cracked asphalt, desert sand, or muddy tracks under the 'Mech's feet. The textured top grips PVA and basing paste. Keep the bevel edge clean for a tidy finish that sits flat on hex maps.

Superglue (cyanoacrylate) bonds ABS well. For heavier metal 'Mech models, score the base lightly with a hobby knife and consider pinning for a stronger hold. Two-part epoxy works well for the heaviest pieces.
