Posting the reply I sent to Jim on Shapeways after purchasing a couple of my cabs. The cab was not quite ready, but good enough for a beta tester to try. This should answer some questions.

Hi Jim,

I was surprised to see your purchase of two cabs. I mainly put the one piece cab up as a product on Shapeways so my son could take a good look at it. I was planning on uploading a file with the four sides and the roof to be printed as separate pieces with correct orientation to make the visible sides as smooth as possible...Some assembly required.

Thanks for being my beta tester. I haven't even printed a cab for myself yet. I did make the walls and roof as thin as I could so you could add acetate for cab windows that would be as close to flush as possible. I've added enough thickness to the bottom of the front so it will fit between the front of the inner cab and the back of the hood without adding any shims. I think you'll have to add styrene shims to the bottom of the backs and sides to position the cab properly against the inner cab.

For the Atlas S2, I believe the back and sides should be the same as for the Proto S1, but I have not yet designed the front cab piece to mesh with the back of the Atlas cab. I need to make sure the curve is correct. That will be my next project after finalizing the Proto S1 cab.

Here's a link to the working drawing for the back of the cab:
https://www.dropbox.com/s/5pxg48ktcrlasey/Screenshot 2017-11-09 17.40.16.png?dl=0 

I was planning on poking out the grab at the top of the Proto cab and using it on the new cab. Same thing for the fuel filler and the lower railings. The only other pieces that need to be added are the wire for the handrails on each side of the door. 

I sized the rear light for an MV 136 clear lens and am planning to file the back of the lens through the silver to make a flat spot and gluing on a small surface mount LED using canopy cement. It's a really nice effect that looks like a bulb lit within the clear lens housing. I've used this technique on an Atlas/Kato RS-3 after swapping out the stock ends for Stewart ends that have the single beam headlight. See here: https://drive.google.com/open?id=0B4ZHV ... FZyTW5jM00

Once you receive your cabs, please provide feedback. I'm not sure how smooth the finish will be without orienting the printing for five flat parts. If something doesn't fit quite right, or needs to be adjusted I can make changes to make it right.

Thanks for ordering my cab. Please feel free to contact me if you have any other questions. I'll also let you know when the Atlas cab is complete.

Regards,
Mike Redden

One correction...

Instead of "For the Atlas S2, I believe the back and sides should be the same as for the Proto S1, but I have not yet designed the front cab piece to mesh with the back of the Atlas cab." it should be "For the Atlas S2, I believe the back and sides should be the same as for the Proto S1, but I have not yet designed the front cab piece to mesh with the back of the Atlas hood

So what's on the Shapeways site right now is not the finished product but merely a preproduction item.

Isn't that all supposed to be taken care of before an item is offered for sale?

I clearly stated in the product description that it was for display only and that the final product would be printed differently to improve the finish on the visible surfaces. I also offered it for sale if anyone wanted to print one.  It appears that Jim wanted to have two printed to get an early look at them. I chose to not deny anyone the opportunity to make a purchase of something if they want it.

Mike,
Great job!  It's nice to see this getting done.  Now I need about a dozen or so...

BTW, there are rivet strips across the roof; Two corresponding to the front and back walls and one between the two with spacing about twice that of the other two IIRC.

Also, can I convince you to do replacement radiators for 0931-0970?  The louvers are much narrower that the later units and consequently there are more of them.  I can't really do these earlier units without them, and, of course the earlier ones are the ones which for me are most needed.

And while we're at it you may want create a version with radio enclosures protruding from the front left window over the hood.  IIRC they're a welded rectangular box which would have to be fitted over the hood.  And if you really wanted to knock yourself out, you could even d the radio to go inside!

Oh, and we could use steam whistles to replace the model's horns, this may require 3 slightly different mountings ...

Anyway, thanks for getting the ball rolling!

Bill Chapin

PS Now I see how Chris is getting his Rt 15 bridge!
