What’s on the workbench part 71 / bolt action, What's on the workbench, WW2 / By burning beard Hello and welcome to part 71 of What’s on the workbench. This week I’ve been testing some STL files from a kickstarter called March to Hell WW2 by 3D Breed. the files have enough detail to tell units apart, without being covered in detail just for the sake of it.The test prints are from the British section. I also found a free STL file of an A9 Cruiser MK1 CS on Thingiverse.
