The Renault UE Chenillette was a utility vehicle designed for the French army and adopted in the mid 1930s. It was never intended as a fighting vehicle, though it was armoured against small arms — it was intended as a light gun tow, and as a resupply vehicle. The cargo bin on the back could be tipped and unloaded from within, without having to expose the crew to enemy fire. Captured examples were widely used by the Germans in a variety of roles, especially in Russia.
This is a 1:100 scale model intended for 15mm gaming, but it should rescale pretty well up to 28mm scales. It's tiny in 1:100, only 29mm long and 19mm wide.
I have included three cargo modules that can be printed separately and be slotted into the cargo bin, or not, as the user desires.
It may be possible to print the 1:100 scale model in FDM, but I have only printed it in resin, so I can make no guarantees there.
