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”.

Medieval bases: old town cobblestones

In the medieval theme, Base Forge makes bases and base toppers for fantasy and medieval tabletop. Every seed gives a unique base at 1:56 scale, as a complete base with sockets for 6 mm magnets or as a topper for round 25 to 60 mm bases and oval 60 × 30 mm bases.

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.

Old town: old cobblestones with round stones and earth joints, sometimes missing stones or cart ruts; a raised pavement of flagstones (sometimes almost the whole base, sometimes a narrow strip), now and then lowered.

Details: drain grates with a channel leading to them, a half-round hole under the pavement, long gutter stones along the curb.

The theme is new (beta): more scenes and matching extras will follow.

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

Printing and painting medieval bases

Which size?

Round 25 to 60 mm, oval 60 × 30 mm for cavalry. The raised pavement covers almost the whole base or only a narrow strip – depending on the seed the model stands on the street or the pavement.

Printing

Resin gives the finest joints between the cobblestones, FDM works with a fine nozzle. Every base is one solid piece, printable without supports; the slots of the drain grate are at least 0.5 mm wide.

Painting

Prime dark, drybrush the cobblestones grey, pick out single stones in warmer tones and wash the earth joints brown. The pavement slabs a lighter grey, the drain grate in dark iron.

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.
