A 3d printed 800 class for 00 (and a WLWR goods loco)

I ran off a quick test print of the new smokebox door last night, Id consider that a success, it really does change the look of the loco (donor N class kindly loaned by @GSR 800)

Excellent work Killian, as always!

Really is transformative.

Maedbh has had her wheels painted. Needs a little bit of weathering!

Might make up some brake cylinders for her at some point.

800 class build:

Going to put this up as a recap for the 800 build and to give a better idea of assembly for 3d printed locos. Here's the loco as arrived, with donor chassis fitted. Only thing added at this point by me was smokebox wheel and handrails.

Handrail holes are modelled but require some drilling out.

Smokebox door wheel with some brass rod (0.6 iirc) for the dart.

Holes for handrail knobs being drilled out. 

Same again, wouldn't advise having the model so close to a ledge!

Handrails and rodding added. May redo some of the handrailing at some point.

Buffers, nameplates, numberplate came from SSM. Nameplates and numberplate can be sourced elsewhere iirc, but I'll have to find the manufacturer. Killian also offered to print the buffers. Safety valves are from the Royal Scot. Windows are supplied by Killian. Vacuum pipe was one I found in the spares box!

Bit of a jump here to the painted model! Lining was HMRS LNER lining, which I found to be quite good. Paint was mid brunswick, I'll edit in the code, I think I posted it on this thread before. The body is all in one piece, so painting and lining takes patience.

Next up was the bogie/front end modification. I chopped the bogie and placed an insert, others have simply drilled out a new slot for the axle for the extra length.

Added some faux frames to improve the air gap

More up to date, painted the wheels. The Scot chassis is not as "getatable" as more modern designs with plunger pickups for the base keeper plate, which means you have to be very careful when removing the drivers. If doing this, I would remove the body entirely, loosen the motor holder and give the wires some slack to save any resoldering!

Overall I found it quite easy to detail the print and painting was less difficult than I had thought initially. One thing I did have to do was file down the weight in the tender somewhat as the tender body wouldn't sit flush. On that note, I may do something about the loco/tender gap at some point in the future.

More recently I've come across photos that show Maedbh with the handrails polished brass rather than painted black, though regulator rodding, steam pipes and the upper handrail on the smokebox were painted black. So today I got a package with brass rod, handrail knobs and a whistle. No rest for the wicked..
