I posted ("shot") first and "questioned" later. After Conducttor's reply I went online to see what was available for 3d printers in the under $500 range. There are a number of such printers available, but the end product, while fairly good is, not any where near to what I want to produce for TT parts in terms of detail and quality of detail. Nearly all of these cheap machines run at about 100 microns of resolution. Apparently you have to get down to around 50 microns to get a good end product. Then there's the issue of the time it would take to produce a part at such level of quality detail. At this point it appears that the capable machines, as Richard B points out, are well into four figures.

Hopefully Richard will let us know how his $99 little wonder 3d printer works out. The web site linked by Richard says stuff can be printed out down to 42-43 microns! Hope springs eternal!

At Kickstarter is a project for yet under $500. I think about a purchase of the big brother Kudo3D Titan 2. - we send worldwide :wink:

I tried to find suitable trucks and drive for the engine and found Tillig's BR103 close enough (Kuehn's BR103 could be another option). Maybe not 100% perfect, but within my tolerance. The trucks need new (smaller) wheels.
The frame needed some extension and adjustment for the fuel tank.
The pictures show the shells, the frame, the trucks, and comparison of BR103's and PA's sideframes.







When you get the chance, could you go a little more into detail as to how you modified the BR103 chassis, as I am planning on trying to get at least one ALCO PA in my fleet in 2018.
