Caledonian 812 / 652 3000 Gallon M2 Tender (4mm, 00, EM, P4)
The toolbox and buffers are joined to the top of the coal seat, clip them off and use as needed. There is a thin beam on the insides of the tender sides towards the front to give the tool box some purchase.
There are some 1mm thick 'stretcher' bars underneither, clip these off carefully, they just help with 3D print stability. Other than adding some handrails (holes already piloted) and couplings there isn't much to say or instruct, most of it is done for you, buffers and toolbox are sprued to the tender top. Feel free to add/remove or replace details as you see fit.
Cab to tender doors for example have been ommitted as thin bits of brass or card would not be over-scale as a 3D print would.
You could fill the insides with weight or electronics, large cut outs have been designed in for this purpose.
