This is a 1/87 scale model of Soviet/Russian boxcar series 11-270. It's general dimensions and big details are modeled rather precise, but undercarriage equipment are somewhat symbolic and rough.
Assembly is shown on the following picture:
I cannot stress this enough: the bed must be really flat, or you need some compensation mechanisms, like level sensor and mesh bed leveling enabled. Good adhesion is a must for this thin and detailed print.
2 versions of car can be printed - with ladders and hatches on roof (use "top v2", "ladder h" and "ladder v") and without (use "top v1")
bottom is modeled for Mehano american bogies with integrated couplers. Other bogies with M4 screw will fit. M3 screw will fit when fixed by a nut.
If bridges print well on your machine, ladders can be printed in one piece with top and front sides.
Doors are movable but might require some filing. They are symmetrical and will fit upside down. v1 and v2 only differ in position of decorative plate for lock.
Bottom ladder (ladder 3) is movable (can be folded) but since it can fall off during travel, it should better be glued.
