This 3D printed hut is made in a 2 colour combination of brown and black PLA and comes as two pieces and a seperate set of glazing.

Important Information:

• This model is unpainted and ready for customization or can be used as it is.

• Due to the nature of 3D printing, slight layer lines will be visible if viewed closeup but look great at normal viewing distances.
• Small imperfections such as bumps, blemishes, or stringing (thin plastic strands) may occur. These can often be removed with light sanding, a sharp craft knife, or gentle heat (e.g., a hairdryer).
• The underside of the print may not be perfectly smooth and could have white patches due to the adhesive used during printing.

It's easy to paint and will be a nice addition to any layout, easy to use normal car primer and acrylic paints. 

The model is shipped from stock and is ready to paint.

We print and make our own models here in the UK and the sale is for the unpainted building and laser cut glazing.

Finishing: They are unassembled and ready for you to prime and paint. We do our very best to remove support marks but some fine sanding may be required. All pieces and parts come unprimed and unpainted with all supports removed. Sadly, we can't be held responsible for breakages once your item has arrived. However, if the piece is broken in the post, please provide images and we will of course see what we can do to help. 

Please note: Dimensions are approximate and may vary slightly. O-Scale figures are shown for size comparison and can be bought separately from our other listings

FAQ – Product FAQs

Frequently Asked Questions – 7mm Corrugated Steel Workshop (O / NG7)

What scale is this workshop designed for?

This corrugated steel workshop is designed for 7mm scale layouts and is suitable for O gauge and NG7 model railway setups.

What are the overall dimensions of the building?

The approximate footprint of the building is 90mm x 61mm, and it stands about 72mm high. Dimensions may vary slightly due to the 3D printing process.

What material is the workshop made from?

The workshop is 3D printed in PLA plastic, using a two-colour combination of brown and black to bring out the corrugated steel detail and structure.

What exactly is included in the package?

You receive the unpainted 3D printed workshop in two main pieces, plus a separate set of laser-cut glazing for the windows. Figures, scenery and any other items shown in photos are not included.

Is the model pre-painted or finished?

No, the model is supplied unassembled, unprimed and unpainted. It is ready for you to prime, paint and weather to suit your own layout, or you can use it as-is if you prefer the raw printed finish.

Where is the model produced and shipped from?

All models are designed, printed and made in the UK and are shipped from stock, ready for you to paint and install on your layout.

Why can I see fine lines on the surface of the model?

The visible lines are normal layer lines from the 3D printing process. They are usually subtle at normal viewing distances on a layout, but can be more noticeable when viewed very close up.

There are small bumps or stringy bits on the model. Is this a defect?

Small imperfections such as bumps, blemishes, or thin plastic strands (stringing) are a common part of FDM 3D printing. These can usually be tidied up easily during your preparation before painting.

The underside of the building looks rough and has white patches. Is that normal?

Yes. The underside may not be perfectly smooth and can show white patches caused by the adhesive used during printing. This is normally hidden once the model is placed on your layout.

What should I do if the model arrives damaged in the post?

If your workshop is damaged during shipping, please take clear photos of the damage and contact the seller. They will review the images and see what can be done to help. Breakages after safe delivery, however, cannot be covered.

The parts don’t seem to fit together perfectly. How can I fix this?

Minor fit issues can usually be solved by gently cleaning up mating surfaces with fine sandpaper or a small file. Check for any stray stringing or small bumps on the edges and remove them carefully before test-fitting again.

There are visible support marks on the model. Can I remove them?

Most support marks are removed before shipping, but a few fine marks may remain. These can be smoothed with light sanding using fine-grit sandpaper or a gentle scrape with a sharp craft knife.

Can I use heat to tidy up stringing or rough areas?

Yes, gentle heat can help. A quick pass with a hairdryer on a low setting can soften thin strands of plastic so they can be removed more easily. Avoid prolonged heating, as PLA can warp if overheated.

What if the glazing pieces don’t sit flat in the window openings?

Check that the window openings are free from stray plastic. Lightly sand or trim any high spots, then test-fit the glazing again. It should sit flat with minimal pressure once the openings are clean.

How do I prepare the model before painting?

Before painting, it’s best to:

• Carefully remove any remaining stringing or bumps with a craft knife.
• Lightly sand any obvious layer lines or support marks.
• Brush off or wash away dust and let the model dry completely.

What type of primer should I use?

Standard automotive (car) primer works very well on PLA and gives a good key for your top coats. Apply in light, even coats to avoid obscuring the fine corrugated detail.

Which paints work best on this workshop?

Acrylic paints are recommended for colouring and weathering the model. They adhere well over primer, dry quickly, and are easy to layer for rust, grime and soot effects on the corrugated steel.

Should I paint the model before or after assembly?

Many modellers find it easiest to do a test fit first, then paint the main pieces separately, and finally glue them together. This helps you reach interior edges and avoid visible unpainted areas.

How do I fit the glazing without making a mess?

Use a clear, non-fogging adhesive such as a small amount of canopy glue or a similar clear craft glue. Apply sparingly around the frame, press the glazing into place, and wipe away any excess before it dries.

Any tips for realistic weathering of the corrugated steel?

For a convincing industrial look, try:

• Dry-brushing lighter metallic tones on the ridges of the corrugation.
• Adding rust streaks with thin brown and orange acrylic washes.
• Using dark washes or powders around doorways, roof edges and window sills to suggest soot and grime.
