Frequently Asked Questions (HO Scale)
Are these items resin or filament?
Most loads and detail items are printed in high-resolution resin; structures may use filament or resin depending on strength needs.
Do items come painted?
Most are unpainted unless marked otherwise (such as the weathered pipe load), or they are part of our new “Ready-To-Run” range.
Can you print in OO/N/TT:120 scale?
Yes — all products are available in multiple scales.
Can I request a custom size?
Absolutely — contact me with measurements or prototype references. This model of a HO Scale Workshop was custom designed and 3D printed for a customer.
