We recently designed, manufactured and intalled these four electronic 1/16th scale tank models as part of the new WW2 War Stories exhibition at the Tank Museum in Bovington.

After CAD models of both the M4 Sherman and Churchill tank in four variations were complete the models were constructed from various 3D print methods with laser cut ply and aluminium hulls. Each has its own specific actuating mechanism so the hard work was to ensure all function over time with almost constant visitor use. As the exhibit had to be Covid safe all the planned push buttons were replaced with ulrasonic switches.

The project was such good fun that we even had to build one of our own for the workshop.
