Follow this link and search for "model railroad", it searches all the 3D STL file websites. Many of the STL files are free to download and use. Read the disclaimer on the file concerning reselling the printed products. They are fairly open about sharing.

Don't know about modifiying a cad file. For cura it has to be a stl file. You could probably go to the site for designing 3d prints.
You can use a multiplier in cura from one scale to another. Go online and get the table. Then if the print is sized for HO you enlarge it by a certain percent from the table. They have it organized so you can do any scale.
Holy Moly... I posted this almost 3 years ago. I don't recall seeing any responses so I wound up making the 3D files available from my home server. I recently moved them over to an online forum as my server was continually slammed. There are around 180 O-Scale items available... with 100 or so of them having the original CAD files as well as the .stl(s). It's not just about re-sizing an .stl to fit a particular scale but more importantly the abilty to modify the CAD file.

RR_MelIf you still want a tower make your own from brass ladder stock, I buy my brass ladder stock from Oregon Rail Supply (#142), Precision Scale (#31327) or Integrated Signal Systems (B117).
Mel, I eventually ordered one from Shapeways for just a few dollars. That was when I first started my layout. Mine is not nearly as tall or as impressive as yours.
Today, I believe I would attempt to make my own.

rrinker Same witht he reverse, scaling up from a smaller scale. The smaller details will have been oversize to make them work in the smaller size - when scalled up from N or HO to O, they will be grossly oversized. So it's not quite as simple as just scaling up or down, it also takes some skill to adjust for things like that. --Randy

Yes, exactly.

York1 I think one of the issues with using full scale drawings that are then scaled down is that small thin parts, such as pipes, in the full size become impossible to print to small scales on cheaper printers. I know my son-in-law tried to print me a radio tower. The cross pieces that were true to scale were so thin they didn't print correctly.

Yeah, I don't see MR getting involved with that. If you want to offer up designs to people for free, stick them on your personal web site. Advertising things for sale here is not allowed, but free things seem to be OK as long as you are not advertising a business. There is a huge thread full of pictures of various vintages that you can scale and print to make signs for on structures or billboards that's been around for years. A general thread on "cool 3D models to print yourself" is IMO nothing different, though the powers that be may see it different somehow.
I seriously doubt MRR or Steve would want to get involved. Far too many issues.
Sorry.
Maybe i am out of touch but i was under the impression anything drawn in 3D cad was full size in the drawing then scaled down for printing. So if an I beam was 22' long you drew it 22' long which makes it easy for dimensions because there is no scaling like us engineers used to do with a scale ruler three sided with several scales on it. Then the software scales it down for 3d printing of the part. I almost bought a 3d printer so I could easily make PRR signal bridges but then thought about the learning curve for the software and scrapped the idea. I also have no idea how delicate the finished structural work would be and does the plastic cover with paint or does it bead up. Too many unknowns for me but it does have potential
Actually a print parts library isn't a bad idea. With little printers like the anycubic that do a nice job, a library would be helpful.

shapeways is a bit of a bear to negotiate when looking for scale stuff. Sometimes you have to look for the the general scale ratio and others by the scale name. I find a lot of interesting parts to add to the must buy list that way. Definitely the future for small production runs and decreased warehousing

the previous poster said it all, you have to reslice the figures anyways, so scaling adds another click, and very little time ..
Why not just resize models that are in other scales? You can easily scale up any model to O scale in any modeling or slicing program. That’s what makes 3D modeling and printing so versatile.

The easiest way to get in touch with Steven Otte is to send him a Personal Message (PM). To do that, go to the top of the General Discussions page and click on Steven's picture beside the first post. That will bring up his profile and there is a "Start Conversation" icon in the upper right.
If he sends you a PM back, you will have to monitor 'Messages' which is under your name on the top right of this page. He may choose to answer directly on the forum.

I'm just a dude with a bad back having a lot of fun with model trains, and finally building a layout!
Dennis,
While I don't have an answer for you, I want to welcome you to the forum. As Mel said, your first few posts are moderated, so they take a while to appear. That goes away pretty quickly.

Hi Dennis,
Welcome to the forums!!
I did a quick search of the Shapeways site and was surprised to see that they didn't have a section for O scale train parts on their marketing page. That didn't sound right, so I did a general Google search for O scale 3D printed train parts and one of the first listings was Shapeways!
Here is a link to their O scale listings:

I'm not sure if you have already seen the listings.
Cheers!!
I guess by now you have figured out your first few posts are delayed.I’m into CAD (since 1985) using DesignCAD 20 and it doesn’t do 3D and I don’t have a 3D printer so I haven’t looked into 3D so far. I could upgrade to 3D pretty cheap. Your O scale drawings could be easily converted to any scale in a 3D CAD program.Awhile back I was kicking around making a 3D drawing of an Athearn Diner interior but found it easier to scratch build it because I only needed one diner. By the time I did the upgrade and the printing costs it was well over my hobby budget.I do almost all of my scratch building drawings on my CAD and post them on my Google Drive accessible to the public, you could do the same. I make all of my drawings 1:87 scale for easy full size templates for my scratch building. I also post them on my blog along with schematics and Arduino Sketches.

Hi,
I'm just joined cs.trains and this is my first post.
I have found it difficult to find much in the way of Model RR O-Scale 3D *ready-to-print* items anywhere on the internet. HO, N, Z yes... but, not O.
I am a retired software developer so I can get around the internet pretty well. I am very well aware of thingiverse and like websites... still, ready-to-3Dprint O-Scale is rare.
Is it acceptable to give/share not-for-sale, free, non-copyrighted O-scale .stl/.svg files with the modeling community here (HO could resize the files if they like)? Would cs.trains like to have a library of ready-to-print files for their members?
I have a word doc with what I have (I named it O-Scale Catalog) but I don't want to attach it... lest I make some angry.
