At the print-testing stage are the STL files for GWR "Concertina" 70ft corridor stock.
The first two types are C27 All Third and D43 Brake 3rd.

Screenshots of the files as rendered from OpenSCAD are attached and photos will appear as the printing progresses (the bolection mouldings are separate inserts and not shown in these shots) .

If these are carriages you would buy and would like to see offered as kits, post a reply here or email Anthony Terranova anthonyterra@hotmail.co.uk who is licensed to produce kits from my STL files.

If there is interest, I will expand the the available types (I am also considering "Dreadnought" stock).

Dean clerestory corridor stock (3 diagrams) and corridor "Toplights" (5 diagrams) are  already at an advanced stage.

My fellow Members, ask not what your Society can do for you, ask what you can do for your Society.

After a couple of months of delay, working on three additional LNER Gresley coaching stock (D4, D23 and D212) and several BR standard wagons (all intended for eventual release as kits by New Land 3D) I have now returned to printing the GWR Concertina stock.

The sides of the C27 All Third and D43 Brake 3rd are shown in primer. It is very difficult to photograph such long items indoors and under artificial light, so only close-up shots of sections of each type are shown, to highlight the detail. These are 70ft carriages (945 mm in G3) and each side consists of five modules, so as to fit, comfortably, onto a 250mm printer bed. The modules include the doors printed integrally, leaving just the bolections around the glazing to be printed separately and inserted into the openings.

Gauge 3 Society members wishing to print these on their own printer for personal use may request a download link from jc@gauge3.info

My fellow Members, ask not what your Society can do for you, ask what you can do for your Society.
