Looking for ww2 packs

Hey all, I’ve just got my 3d printer so i have spent the last few weeks searching for things that I need. For example this package of models https://www.thingiverse.com/m_bergman/designs has kept me occupied for a long time (converting 1/100 scale to 1/72 and printing.

What i’m looking for is packs of military stuff (equipment, vehicles etc, all minitures) that come preferably free.

I have been looking for a couple weeks now, but im sure there are some awesome packs people would be aware of floating around
