HO Scale Flatcar

First project when I got my 3D printer. A simple flatcar. Prints in two pieces, with the deck being separate from the frame. It was still early days for figuring out how to install coupler gearboxes and attaching trucks, so things were pretty barebones.

Eventually, I need to revisit that model and add some detail, along with holes for attaching the coupler gearboxes. Currently, I just put them into their slots and then use a pin vise to add 2mm holes to attach them with M2 screws.

HO Scale 40' GS Gondola

This was my second piece of rolling stock that I modelled. Loosely based on a PRR design, like the flatcar. This is another one I need to revisit and add some detailing along with modernizing the coupler gearbox mount.

HO Scale NA Cabin Car

When I came across a schematic for the PRR NA cabin car, I had to model it. It's just way different than a regular caboose.

After a few test prints, this was the most successful one.

HO Scale X35 Boxcar

I like boxcars, so why not model and print a boxcar?

It came out better than expected, except for where the roof meets the body.

O Scale B6sb locomotive

This is a work in progress.

I left off at the prototype stage of printing it efficiently and trying to adapt the CAD model to reality to fit a motor and gearbox. There's still a lot of things to do before it can be realized:

• Source a motor.
• Turn brass wheels.
• Source or build a gearbox.
• Fabricate coupler bars and pistons from brass.

Like all hobbies, this is prone to cycles. I'm not in a model railroading cycle currently.

I left off just after getting a metal lathe and beginning to get the hang of turning wheels. Maybe I'll pick it back up again next year.

Initial draft with details.

The draft after it met reality (was printed) and the model had to be modified to accomodate a motor and drivetrain of some sort.

The prototype result is kind of rough. Maybe the next time I print the model I'll figure out how to make it look less rough.
