Frequently Asked Questions – OO9 / OO Workshop with Lean-To (Unpainted PLA)
Is this workshop suitable for both OO9 and OO standard gauge layouts?
Yes. The building is designed with OO9 narrow-gauge layouts in mind, but the footprint and proportions also sit comfortably alongside standard OO scenery as a small workshop, store, or yard building.
What are the exact dimensions of the model?
The workshop with lean-to measures approximately 78mm long × 49mm wide × 67mm tall, making it a compact structure that fits easily into sidings, quarries, and industrial scenes.
What material is the model made from?
The building is 3D printed in bio-plastic (PLA). It is supplied fully printed and cleaned, ready for priming, painting, and installation on your layout.
Does the model come painted or finished in any way?
No. The workshop is supplied unpainted so you can finish it to suit your own layout. Any painted examples shown in photos are for inspiration only; you will receive a bare, unpainted model.
How can I attach the building to my layout baseboard?
You can fix the workshop to your baseboard using a small amount of suitable adhesive such as PVA (for scenic boards) or a thin layer of contact adhesive. Many modellers simply sit it in place without glue so it can be moved or repositioned later.
Is this model suitable for beginners to model building and painting?
Yes. The workshop arrives as a single, support-free piece, so there is no complex assembly. With basic priming and painting, even a beginner can achieve a convincing result, and more experienced modellers can add extra detailing and weathering.
What should I do if my model arrives damaged in the post?
Please handle the model with care when unpacking. If it does arrive damaged, take a clear photo of the damage and contact the seller. They will work with you to put things right.
Can I use enamel paints on this PLA model?
Yes. The model can be painted with both acrylic and enamel paints. Applying a suitable primer first will help either type of paint adhere better and give a smoother finish.
Do I need to wash or clean the model before painting?
The model is supplied cleaned and support-free, but it is still good practice to give it a quick rinse in warm, mildly soapy water, then let it dry fully. This removes any dust or handling residue and helps primer and paint stick well.
Is light sanding really necessary, and what should I use?
Only a little light sanding may be needed, usually on any slightly rough edges or print lines. Use fine wet-and-dry paper or a fine sanding stick, and work gently to avoid flattening the corrugated roof or brick detail.
Can I cut or modify the PLA building to add doors, windows, or lights?
PLA can be carefully cut and drilled, so you can add extra details if you wish. Use sharp tools, work slowly, and support the walls from behind to avoid cracking. Always test on an unseen area or offcut first if you are unsure.
What kind of primer should I use on PLA?
The model takes standard car primer very well. A light mist coat of automotive acrylic primer (grey or red oxide) is ideal. Apply several thin coats rather than one heavy coat to preserve the corrugated steel and brick detail.
How should I paint the brick walls for a realistic finish?
After priming, apply a mid-brick base colour with acrylics, then:
- Add a lighter dry-brush to pick out raised brick edges.
- Use a thin, light mortar wash (very diluted paint) to settle into the joints.
- Finish with selective darker washes to suggest soot, damp, and age.
What is the best way to paint the corrugated steel roof?
Prime first, then use a dark grey or muted metal base coat. Once dry, lightly dry-brush with lighter greys or rusty browns along the corrugations. A thin rust or grime wash towards the eaves and around the lean-to junction helps bring the roof to life.
How can I glue extra details or figures to the PLA surface?
PLA can be glued with superglue (cyanoacrylate). Use a small amount on clean, dry surfaces. Hold the parts together for a few seconds while the glue grabs, and avoid excess glue which can frost clear parts or leave shiny marks.
Do I need to seal the model after painting?
Sealing is optional but recommended, especially if the model will be handled. A light coat of matt or satin clear varnish over fully dried paintwork will help protect the finish and unify the sheen across different paints and weathering layers.
