This is a resin printed 6-8mm Scale MRRV Mech Repair Vehicle. It is ideal for a range of post modern and sci fi games, if you get 3 of them.. they can be modelled fully enclosing a mecha!
These are 3d printed as there are "hinges" built into the model that allow it to fold out and unfold (a paperclip cut down is ideal for this purpose) or you can, of course, simply model it how you like.
