Good looking figures. There are only seven heads total for 13 figures, so some will have to be used for multiple figures. One of the mechanic heads looks like he is wearing a German helmet with a sniper shield. I thought maybe it was included in the zip file by accident, but then I saw it in the preview images, so I am guessing it must be a "captured" German helmet he is wearing, trying to be funny or maybe just because the sniper shield offered a little extra protection when working on the tank in a combat zone. The seventh head looks like a helmet with camo strips on it.
The only drawback is that most of them come out at an odd size. The heads came out massive and the figures came out tiny for the most part. The 42MM files can be scaled to 1500% and they will come out at 1/35 and look clean (one of the benefits of resizing digital 3D files, not much in the way of degradation when resizing things) The 52mm files you can resize to 1125% to make them 1/35. Once you have the 1/35 files saves, you can resize those to 218.75% to make them into 1/16 scale figures.
the two zip files are defective and cannot be unpacked
Love these models and they print wonderfully. Positive critiques: wish the facial details could be slightly better and some of the US tank crew had to be resized to 52mm (they were very very small after unzipping). But I really liked them and am thinking about becoming a patreon member!
