• Height: 160mm
• Width/Depth: 73mm square

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

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).

FAQ – Product FAQs

Frequently Asked Questions

What is this water tower made from?

The water tower is 3D printed in PLA plastic, using a three-colour combination of brick, grey, and black. It is supplied as a single solid piece.

What are the dimensions of the model?

The approximate dimensions are 160mm in height and 73mm wide by 73mm deep (a 73mm square footprint). Please allow for slight variation due to the 3D printing process.

Is this water tower suitable for G-Scale layouts?

Yes, it is designed with G-Scale layouts in mind. G-Scale figures shown in photos are only for size comparison and are available separately in other listings.

Does the model come painted?

No, the model is supplied unpainted. It is printed in brick, grey, and black PLA so you can use it as is, or prime and paint it to suit your layout.

Is any assembly required?

No assembly is required for this water tower. It comes as a single piece, ready to place on your layout or to prime and paint as you wish.

What preparation do you do before shipping?

All items are cleaned and cured by hand, with all supports removed. We do our best to remove support marks, but some fine sanding may still be required before painting.

Why can I see layer lines on the surface?

Visible layer lines are a normal feature of 3D printing. They may be noticeable close up, but are designed to look great at normal viewing distances on a layout.

What kind of imperfections should I expect?

You may see small bumps, blemishes, or thin plastic strands (stringing), and the underside may not be perfectly smooth and can have white patches from the adhesive used during printing. These are cosmetic and can usually be tidied up easily.

How can I remove small imperfections?

Minor imperfections can often be removed with light sanding, a sharp craft knife, or gentle heat such as from a hairdryer. Always take care and work slowly, especially around fine details.

Why is the underside not perfectly smooth?

The underside of the print sits on an adhesive surface during printing, which can leave slight texture and white patches. This is usually hidden once the model is placed on your layout or mounted on a base.

Can I use the model outdoors?

The tower is printed in PLA, which many modellers use both indoors and outdoors. However, PLA can be affected by heat and prolonged sunlight, so for outdoor use it is a good idea to prime and paint it thoroughly and avoid placing it in very hot, direct sun where possible.

What should I do if the tower arrives damaged from the post?

If your item arrives broken, please take clear photos of the damage and packaging and contact us. We will review the images and see what we can do to help. We cannot be responsible for damage caused after safe delivery.

My tower has visible stringing or wispy strands. How do I fix this?

Stringing is a common 3D printing artefact. You can usually remove it by gently:

• Snipping the strands away with a sharp craft knife or fine snips
• Lightly sanding the affected area
• Carefully applying gentle heat (for example, a hairdryer on low) to soften and shrink fine strands

Work slowly and avoid overheating the plastic.

The base of the tower rocks slightly on my layout. How can I level it?

If the underside is not perfectly flat, you can:

• Lightly sand the bottom on a sheet of fine sandpaper placed on a flat surface
• Mount the tower on a thin baseboard or scenic card and blend the edges with ballast or scenery materials

This will help it sit firmly and look integrated into your layout.

There are small bumps or support marks. Should I be worried?

Small bumps or support marks are cosmetic and normal for 3D prints. They can usually be smoothed with fine sanding before priming. They do not affect the structural integrity of the model.

The dimensions are slightly different from those listed. Is that normal?

Yes, the dimensions given (160mm high and 73mm square) are approximate. Small variations can occur due to the 3D printing process, but these are usually minor and do not affect normal use on a layout.

What if I accidentally drop and damage the tower?

PLA parts can be damaged if dropped, especially on hard floors. We cannot be held responsible for breakages after delivery, but minor breaks can often be repaired with suitable plastic or cyanoacrylate glue. For severe damage, please contact us and we will advise on possible options.

Do I need to prime the model before painting?

Priming is strongly recommended for the best paint adhesion and finish. Although the model can be used as printed, a good primer coat will help paint grip and reduce the appearance of layer lines.

What paints and finishes work well on this tower?

The model takes standard hobby paints well. For example, you can use:

• A red primer (such as Halfords red primer) over the brick areas
• An ink wash to bring out the brick and panel details
• Matt black acrylic for metalwork and weathering

Always test on a small, inconspicuous area first.

How should I prepare the surface before painting?

Before painting:

• Inspect for any bumps or stringing and gently sand or trim as needed
• Wipe the model lightly with a soft, dry cloth to remove dust
• Apply a thin, even coat of primer and allow it to dry fully

This will give you a smoother, more durable finish.

Can I leave the model unpainted on my layout?

Yes, you can absolutely use it straight from the box. The brick, grey, and black PLA already give a pre-coloured look. Painting is optional, for those who want extra realism or weathering.

Any tips for weathering the tower to look more realistic?

A simple approach many modellers use is:

• Prime the model, especially if you want to change the base colours
• Apply an ink or thinned paint wash to pick out brick joints and panel lines
• Use dry-brushing with lighter tones to highlight edges
• Add matt black or dark brown acrylic around the top and down the sides to suggest water stains and soot

Build up effects gradually so you can stop when it looks right on your layout.
