Landshipmodeling recently released the Soviet D-37 and DT-45 railcars. Landshipmodeling is an American brand that offers .stl files so you can 3D print their models yourself. The advantage is getting the files at a very low price; the disadvantage is actually being able to print them. Here’s the link to their website: https://landshipsmodeling.com/collections/digital-products. I’m certainly not a printing pro, but overall, it went pretty well, with a few minor flaws that I think I’ve corrected. There are very few parts to print because it’s a fairly basic vehicle: two hull halves, the turret, the four headlights, the machine guns, the door handles, the front and rear hitching system (modified), and that’s it. The only correction I made was to the gun mount, which is initially just glued onto the turret and therefore remains fixed. I also re-engraved some lines that weren’t deep enough.
