Scene

Base size (mm)

The larger the base, the longer it takes to compute: more area, more details and more extras. How long exactly also depends on the scene.

Base*	Time
25 mm	1×
32 mm	~1.5–2×
40 mm	~2.5–3×
50 mm	~3–5×
60 mm	~4–8×
60 × 30 oval	~3–3.5×

A 25 mm base usually takes just a few seconds in the browser; 50 and 60 mm can take a minute or more, depending on your device. You can stop the computation at any time with “Cancel”.

Tip: for large bases, try out seeds with the “Draft” quality first.

* rough values, “Standard” quality with all extras; without extras and for scenes without extras (e.g. old town) it is much faster.

Full base for 6 mm magnets The complete base at full size instead of just the topper, 4 mm high. Hollow underneath with sockets for 6 × 2 mm magnets: one in the centre on 25 mm, two on 32 mm, four at the rim from 40 mm and on the oval base.

Hero base (raised)Beta For special, unique models: a much higher topper so the model stands above the others. Depending on the scene it stands e.g. on the trench rim, a concrete tank barrier, a flight of stairs or a house ruin.

The oval base is not available for this scene.

Seed

The same scene, size and seed always give the same result.

Quality

Quality sets how finely the surface of the base is computed.

	Grid	File*	Time
Draft	0.16 mm	~10 MB	1×
Standard	0.11 mm	~20 MB	~2×
Fine	0.08 mm	~40 MB	~5×

The finer the level, the sharper small details such as wood grain, cobblestones, seams and small extras become. In return, the file gets larger and computing takes longer.

With the same seed, the layout of the base stays the same (terrain, walls, paving, most extras). Small parts such as single casings may lie a little differently or be missing at another level.

Tip: try out seeds in “Draft” first, then build your favourite base as an STL in “Standard” or “Fine”.

What is Base Forge?

Base Forge is a free generator for 3D-printable bases and base toppers for tabletop wargames in different worlds. Every theme brings its own scenes and extras. Every seed gives a unique base at 1:56 scale that you download as an STL file: as a complete base with sockets for 6 mm magnets, or as a topper you glue onto a round 25, 32, 40, 50 or 60 mm base or an oval 60 × 30 mm base. You print it yourself on a 3D printer.

Full base or topper: the complete base at full size (4 mm high, hollow underneath, sockets for 6 × 2 mm magnets) or just the topper to glue onto bases you already have.

Trench warfare: trenches and mud in First World War style, with helmets, spent casings, sandbags, skulls and bones.

Medieval (beta): old town street with cobblestones, a raised pavement, drain grates and cart ruts.

Everything is computed right in your browser – nothing is uploaded, there is no sign-up and there are no cookies.

Frequently asked questions

Which base sizes are supported?

Round 25, 32, 40, 50 and 60 mm, plus oval 60 × 30 mm (some scenes look a little different on the oval base). As a full base, the STL has exactly this size. As a topper it is slightly smaller (24.1 / 29.8 / 37.9 / 47.5 / 59.5 mm, oval 55.8 × 29 mm) so it sits neatly on top of an existing base without overhanging.

Does the scale match my miniatures?

All scenes and extras are designed at 1:56 scale, which suits common 28 mm tabletop wargame miniatures.

Which games do the bases fit?

Base Forge is not tied to any particular game: make the bases you like – theme, scene, size and extras combine freely. They fit any tabletop wargame with round 25 to 60 mm or oval 60 × 30 mm bases and 28 mm miniatures, whether infantry, heroes, monsters or cavalry.

What is the best way to print the STL?

A resin printer works best for fine details such as wood grain, cobblestones, seams and small extras. An FDM printer works too, ideally with a fine nozzle and a low layer height, but small details will come out coarser. Everything is built to print without supports.

How do I attach the base, topper and model?

The full base is ready to use: glue 6 × 2 mm magnets into the sockets underneath, prime and paint. Glue the topper onto an existing base with superglue.

Where does the model stand?

Every scene leaves room for your miniature: a flat, free area to glue it on always stays clear. Walls, ramparts and larger extras only sit at the edge or on one side – never where the model stands.

What does the seed do?

The seed is the number the randomness is calculated from. The same scene, size, seed and extras always give the same base, so you can recreate a base you like or share its seed. Leave it empty to roll a random one.

Can I sell the STL files?

You are free to use, print and paint the generated STLs for personal use. Selling the files or prints is not allowed.

Will there be more themes?

Yes – Base Forge keeps growing: every theme brings its own scenes and extras, and more worlds will follow. New scenes appear automatically in the tab of their theme.
