Lots of pictures incoming! Years ago I made this post about my visit to a train museum in Korea. Since that visit, I've kind of been obsessing over making models of Korean trains. I don't post here much, school has kept me busy, but this is a project I have been spending quite some time on recently. One of my other hobbies is 3D printing, which I kind of got into so I could make my own custom models without dealing with scratchbuilding. Utilizing this second hobby I have just started making my first model, a model of a Korail (Korea Railroad) gondola. I'll go over the process a bit so you can see how this all works. You'd think gondolas are all the same, but I haven't seen any other gondolas quite like these:
I modeled these in CAD software, basing them off another gondola model so I could have some dimensions to work with. I used a Metasequoia, pretty obscure program, but there are a lot of other free programs out there such as Fusion 360 and FreeCAD. I had to do the details by guesswork, studying over pictures. I think it turned out pretty well considering that.
Here it is in the slicer:
I printed this out on my Creality Ender 3 at a 0.08mm layer height. It took about 20 hours, but I was also printing pretty slow. Here's how one of the drafts came off of the printer:
All of the support material left behind:
I drilled and tapped holes to mount some Kato S-2 trucks and Kadee couplers. These Kato trucks are really nice; they have spinning roller bearing caps, roll smoothly, and cost less than $6 a pair, cheaper than most other trucks I've seen. As you can see above, I also included a space for a weight that is hidden underneath a false floor. I used an Accurail 40' box car weight.
Here is the assembled car as of now:
And paired with a locomotive:
Prototype:
Now I have to sand down the layer lines a bit, paint, and add detail parts. It might be a couple months until that next update, because I have zero airbrushing experience and I don't even have an airbrush yet. If someone could point me in the right direction on how to get started, I would appreciate it.
I highly recommend getting into 3D printing if you haven't looked into it already. There's a bit of a learning curve, but it is so worth it. Printer prices are lower than ever, mine cost $200 and there are some that are cheaper than that. Besides making custom rolling stock, it's really useful for making replacement parts. No need to hunt around for brake wheels or boxcar doors when you can just print them!

Whew, that was a long post!
