3d model resources for 3d printing
Posted by keithcorcoran on Sunday, September 2, 2018 11:15 AM

I'm new to model railroading. 

My wife has a nice size Cristmas Village display (about 8'x5') and seems like every other year we buy a cheap toy train to put on it but end up disappointed because there's no layout variation, engines are battery powered and scale is terrible.

This year we're biting the bullet and picking up a RTR O-scale set and starting to transition accessories and figures over to o-scale or close.

I went to a couple of local shops and all suggest a RTR set vs trying to buy used parts to piece together a set.

Staying on topic...

Since I have a 3d printer I would like to try to 3d print a lot of the o-scale accessories to keep costs down a bit (at least initially). I've found a few houses I'm in the process of printing but I am having an impossible time finding figures.

I did a quick test using a human model I found to work out scale. 

While I wouldn't mind buying some O-scale figures here and there, it seems most available figures are not appropriate for winter scenes like the ones you can buy from say Lemax or Dept 56 which are way too large for O-scale.

Would anyone happen to know of a source for 3d models like this? (or any free/low-cost model railroad 3d model sources?)

Here is my test print alongside an unknown brand O-scale teenager and trash can. 

I used this model...

Welcome to the forum.  It doesn't look like you post attracted much attention.  Sometimes it gets pushed down on the list by new posts.

The are not a lot of people on the forum doing 3D printing.  One person, I think Mel, has bought figures from shapeways and figured out how do do resin casts of those.   That's not quite what you had in mind, but it cheaper than buying from Shapeways.

Hi Keith:

Welcome to the forums!!     Welcome

Sorry I didn't respond sooner. I hope you haven't given up on us.

Here is a link to Shapeways current offering of O scale figures. There are a total of 1330 (but once you take out the nude women the number goes down significantlySmile, Wink & GrinLaugh).

https://www.shapeways.com/marketplace/miniatures/figurines/?q=&sort=&facet%5BpdcId%5D%5B0%5D=111&facet%5BpdcId%5D%5B1%5D=348&facet%5Bprice%5D%5Bmin%5D=1&facet%5Bprice%5D%5Bmax%5D=2500&facet%5Bprice%5D%5Bfrom%5D=1&facet%5Bprice%5D%5Bto%5D=2500&s=52#more-products

I only went through the first few pages but I did find a few that could pass as being dressed for colder weather.

My suggestion would be to buy a few different figures and then copy them. If you are using them for your own purposes I don't think you would be breaking any laws. Then you can take the figures and modify them by repositioning arms and turning heads, or removing hats if they have them. You could even add your own overcoats by using modelling putty. Brief cases can be cut off. You could modify an arm so that it is holding presents. The presents would be easy to make. Etc. etc.

Have fun

Welcome

I model in HO and I buy a few figures to use for making molds.  I use Preiser male figures and Shapeways females.  The male figures for me are perfect to make molds.  I cut off and reposition arms, legs and heads of the castings then make molds of the rearranged figures, I don’t cut up the masters just encase the molds ware out.
 
I went with nude bald female figures for masters then cut them up and rearrange them like the male figures and make molds of the rearranged figures.  I went with the bald nude females because it is easy to add clothes and hair using plastic putty.  That makes it easy to come up with bunches of different looking females.  Realistically all male figures look alike but females never look alike.
 
I don’t know what a printed figure costs but I figure my HO castings cost about 15¢ to 25¢ each, maybe 40¢ for an O gauge figure.  The mold costs would be very close to the same as HO and I get hundreds of HO castings from $23 worth of resin (32 oz). 
 
 
I haven’t counted my castings but I have over 50 molds each with 2 to four figures per mold.  I think I have made over 600 HO figures for my layout and passenger trains.  I just finished a ten car heavyweight train with 20 to 50 passengers per car.

I configured a woman sitting in a recliner but I haven’t found a place to put her.
 
 
I also make furniture castings.
