40mm Round Wide Lip Slotted Bases

Injection-Moulded ABS Plastic · UK Designed · Hobby Heaven

📦 What This Is

40mm round wide lip slotted wargaming bases made from injection-moulded ABS plastic. The wide lip profile is the standard for medium-based models in Warmachine, Hordes, and Infinity — game systems that require a raised-rim base. Comes with a 27mm slot for tabbed miniatures. Black, ready to prime and texture.

🔧 Material & Build

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 smooth 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 wide lip profile adds 1mm of raised rim around the 30.83mm playing surface — the defining feature of bases designed for Warmachine, Hordes, and Infinity. The lip provides a clean visual frame and helps contain texture materials during application. More playing surface than the 30mm wide lip — useful for scenic work around medium-sized models.

✅ Compatibility

40mm wide lip is the standard base for medium-based models in Warmachine and Hordes — light warjacks, light warbeasts, and larger solos. Also used in Infinity and other systems that specify a 40mm wide-lip footprint. The raised rim profile is a tournament requirement in these systems.

The 2mm slot accepts standard miniature tabs. If you don't need the slot, fill it with green stuff or a strip of plasticard before texturing.

Part of the Open Basing System (OBS)

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.

➜ 30mm Wide Lip Bases — small-based models in the same wide lip profile

➜ 40mm Round Plain Bases — same size, standard edge, for other game systems

➜ Base Converters — adapt between sizes instantly, no rebasing

➜ Other Round Sizes — 25mm, 32mm, 50mm and up in ABS quality

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

💡 From the Workbench

USING THE SLOT

Slide the model's tab through the slot, apply superglue from underneath, and trim any excess tab flush. The 2mm slot width accepts standard miniature tabs. If you don't need the slot, fill it with green stuff or a strip of plasticard before texturing.

BASING WITHIN THE LIP

The raised lip acts as a natural boundary for basing materials. Apply texture paste or PVA and sand up to the inner lip edge for a clean, framed look. At 40mm you have more playing surface than the 30mm wide lip — enough room for small scenic details around the model's feet.

PREP

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

MAGNETS

Glue a 5x2mm or 3x2mm disc magnet to the underside with CA gel. At 40mm there's enough floor area to place the magnet centrally for a balanced hold. Check polarity before the glue sets if you're magnetising a force for tray use.
