3D-printed Treugolnik tyres - realistic tread of period Russian rubber

Tyres are among the most visible parts of an armoured car, yet difficult to render well in injection moulding - a shallow, simplified tread quickly betrays the model's scale. 3D printing achieves a sharp, deep tread pattern and legible sidewall lettering and markings. The Treugolnik brand (Russian for "Triangle") was one of the leading Russian tyre makers during the First World War, and the distinctive herringbone tread was popularly known as "elka" (little fir tree).

The parts are attached with cyanoacrylate glue; before painting it is worth gently cleaning the surface of any print-support marks. A matt rubber finish is recommended, optionally with light pigment soiling for a dusty look consistent with the rest of the vehicle.

About the vehicle - the Mgebrov-R armoured car:

The Mgebrov-R (Izhorsky Mgebrov-Renault) is a Russian armoured car of the First World War, designed under Staff Captain Vladimir Mgebrov and built on a French Renault chassis, with armour fitted at the Izhorsky Plant. Its defining feature was the heavily sloped armour plating of the front section - one of the early applications of sloped armour, giving better ballistic protection with less plate thickness and weight.

The vehicle was operated by a crew of four (driver, commander and two gunners) and was armed with machine guns. The Mgebrov-R was built in small numbers and used mainly on the Eastern Front for reconnaissance and infantry support. Some vehicles were still being rebuilt during the 1917 Revolution. Despite the limited production, the design remains an important example of the early development of Russian armour.
