Based on a prototype at Midsomer Norton. Designed to print largely without support, and "clip-together" assembly.
3d printed wheels and axle included, and if all is printed in PETG, run remarkably well - G1MRA Wheelsets can be dropped in if preferred. The stretcher includes a "box" into which standard car balance weights or other ballast can be added.

3D Model
Print upright as one might expect, requires support (suggest paint-on organic) under the vent at either end only. Slicers will detect other areas claiming to need support - it shouldn't need it.
3D Model
Intended to be printed on end. support needed (I suggest Organic support) under the one end closest to the bed, and to the upper surface of the square in the middle. The two slots ether side are for ease of holding during painting. Currently uploaded as an .stl that I understand causes significant faceting - I will endeavour to overcome this with an updated file in the near future.
3D Model
Print top down, no support required.

3D Model
This is intended to clipped in under the buffer beam and be flexed into the curve of the prototype to plug into the bufferbeam. I found it best to flex it a segment at a time.
3D Model
This part needs to be printed as is, but also "mirrored" to complete the buffer.
3D Model
Two parts required per axle - best assembled using the 3d printed wheel press tool - Alternatively G1MRA wheelsets drop in.
3D Model
One side of the assembly has flats on it - this on the bed should print the links such that it comes off the bed as a complete three link chain.

File notes
Slice from this to avoid faceting on the roof print.
