3D Printed Model Railway Parts

Lineside structures, drawn once at full size and scaled properly — platform sections, retaining walls, tunnel portals, buffer stops, huts and wagon loads. Each one is published only at the scales where it genuinely prints: a retaining wall works from TT up to O, while anything relying on brick courses or window bars stops resolving long before N. That is a nozzle-diameter limit, not a design choice, and we would rather show you which scales work than sell you a blurred one. Print in PLA for structures you will prime and paint; PETG if a piece lives near a window and sees sun.

3D Printed Model Railway Parts — example prices

Worked examples from this category, priced by the same calculator that estimates your own part. Sizes span small to large so you can see how cost moves with the part.

Example guide prices for one unit of each part, by material.
Example part	Size	PLA	PETG	ABS / ASA
Chimney Stack (OO)	14 × 10 × 26 mm	£0.65 – £0.83	£0.69 – £0.88	£0.79 – £1.01
Wagon Load, Coal (OO)	62 × 31 × 16 mm	£7.59 – £9.70	£7.98 – £10.19	£8.81 – £11.26
Platform Section (OO)	79 × 39 × 13 mm	£9.99 – £12.76	£10.47 – £13.37	£11.49 – £14.68
Platform Section (O)	138 × 69 × 22 mm	£50.77 – £64.87	£53.10 – £67.85	£58 – £74.11

Guide prices for a single unit, calculated from the measured geometry of each example model — not fixed quotes. Small parts land at or near the £0 minimum order, and per-unit prices fall with quantity. Your price depends on your own part, its material and its printability. How pricing works.
