Fully scaled and articulated to work on a OO scale train set.

I found a concept for this online but wanted to scale it for 3D printing. The mesh was hard to work with so I rebuilt it from scratch. Along with some variants.

Everything moves and rotates. The turrets are removable and lock in place.

Everything moves and rotates. The turrets are removable and lock in place. The top turrets pull out to unlock a vertical pole which locks the side turrets in place. The top turrets lock in with a simple screw motion.

The smoke stacks on each side also print separately and need gluing on. This creates drain holes for resin.

The barrels are also printed separately.

There’s a 3 segment section too in my collection.

The bogies are a solid object. I'll be putting up some proper bogies for download separately.

Designed for 15mm wheels. But this can be adapted based on the bogie.

Printed fine on my ancient 2k Mars 2 but may need tweaking for parts to fit securely.

I had planned to print and sell my models but… life had other plans. So I’m slowly putting my trains up for download. Maybe other people can make some money off them.
