I’m kicking around a project idea and it requires a NW2 shell or better (cheaper) would be to print one.
I have looked around without luck. Does anyone know where I can find a 3D file of a USAT NW2 hood?
Is there one in a smaller scale that can be enlarged?
Thanks.
Did you call Ro’s ? some times they have shells
I’d like to see the NW2 body shell in LGB Scale 1: 22.5, since I model in a dying scale and I own all the LGB diesels in the body styles that LGB offered, I’m pretty much at the end of what I can buy in that Scale. 1/29 scale is just too small to run on my RR, looks way out of scale when put together.

Landon Solomon has an SW1500 in 1:20.3 that he’s been working on.
I forgot about that! Landon has just scaled up Daniel Noree’s design.
@capecodtodd The SW1500 is very similar to the NW2. Maybe you could borrow the Rear motor housing and cover.
Thanks for the info on the other models, unfortunly 1:32 scale is too small and 1:20.3 is too big. LGB scale is a real pain in the you know what at times, because many of the engines, etc., are not totally to scale either. Getting close with this scale is all that I can hope for at times, but engines and rolling stock need to look inline with LGB people, etc.

I saw that one on Thingiverse by Daniel Noree but it is 1:32. I didn’t know that Landon scaled it up to 1:20.3. That is huge!
Since I want this to work with my USAT engines maybe I can increase the size of the few select parts I need to have them closer to 1:29 ?
Hmmm Now you guys have me thinking that my scheme is possible.
Thanks!
It was funny. I started looking at the file for scaling it up and it was already HUGE! Then I realized I had the wrong one, the 1:20 version.
The front grille part is now printing.
I printed it back in 2016 in 1:29 scale by just increasing the size of each part by 110.3%
I have found this to be very useful and accurate. Great for sizing between scales. I created it using a formula I found online. And so far it has worked well when I have designed things in one scale and wanted to print it in another.
As Dan pointed out he used 110.3 is what he used to go from 1:32 to 1:29. I rounded so not as precise. But so far that chart hasn’t let me down.
That is very handy advice, Thanks.
I printed the front part last night and resized it by the x y z ratios to give me the millimeters I wanted. Does this make sense?
I plan on increasing the sides and top to match.
I hope this works.
If you are trying to match the dimensions of a USAT NW-2 that should work.
I use Stan’s handy converter for scale converter all the time. Well worth the $24.

That makes sense Dan. I created my chart mainly for me working with my own stuff. I usually design in 1:1 and this has worked to get me where I am going.
But that program you are using looks like the ticket. I had to work a bit to find a formula/calculator that would do it by percent. And since I use Matter Control for my resizing its very easy to do so by using the percentages.
But as you state, when you are aiming for a target like and existing chassis its likely gonna be better to size it dimensionally
I was really leaning this way but it doesn’t matter what a rooster thinks.
Trouble with the print! After several hours of printing the top piece of the hood finished and it has a warp on the corner that I don’t think I can salvage. 
UGH…
What would cause that? It seems to happen when I print thicker things like this hood top piece and Dan’s radiator for the GP38. The warp wasn’t that bad on the radiator so I still used it but I think this piece is junk.
My printer is a Geetech Mizar S with PLA filament.
Todd, I have an NW2 shell if you’re interested. Just send me a message.
Todd,
Unfortunately I have little useful guidance on what your issue is since I am an infant when it comes to filament printing.
But my offer stands.
pics? Did the part come free of the bed during print?
