I design primarily for the Interwar and WWII periods, and in 1:100 scale for 15mm gaming.
These days I print models almost exclusively in resin, but wherever it is feasible I design with tolerances suitable for FDM as well.
In the latter half of the 1930s, experiments were made with mounting a 2 pounder anti-tank gun in an open-topped box turret on a Vickers Light Tank Mk.V, to create what would later be known as a tank destroyer.
It would have had the advantages of being relatively cheap, small and easily concealable, and quite fast for its time, and the 2 pounder was arguably the best ATG in existence then. However, it would have been very vulnerable to return fire from virtually anything heavier than a machine-gun.
It was not taken up by the British army, and never went into production. However, that’s no reason not to have a model of it, if only for “what if?” scenarios.
The model comes in separate STLs for three components: the turret and turret plug, and the hull.
