This is an ol time baggage train cart designed for the H0 scale (1:87).
The model is just the top part of the cart. The chassis (the ram) is from "Old railway passenger wagon in scale H0

What you need from UTG is:
1 ram
2 sides of the ram
2 pcs hook
2 pcs other hook (excuse my poor English)
I have redesigned the wheels and the buffers a bit.
The complete WAGON.STL is not printable - it is just for visualisation.
I've included two versions: 0ne is complete body and the second is split in parts, so that you could flatbed print it.
I think the model is a bit larger than the HO - 1:87 scale and if someone would like I can take some time and scale it down for perfect HO scale fit.
