German Anti-tank pak 40 1-16 model 3D print model

Model at 1:10 and 1:16 og german PAK 40 The 7.5 cm Pak 40 (7,5 cm Panzerabwehrkanone 40 - 7.5cm armour defence cannon [19]40) was a German 75 millimetre anti-tank gun of the Second World War.

The gun was developed in 1939–1941 and entered service in 1942. With 23,303 examples produced, the Pak 40 formed the backbone of German anti-tank guns for the later part of World War II, mostly in towed form, but also on a number of self propelled artillery such as the Marder series of Panzerjäger

A modified version of the gun designed specifically for vehicle-mounting was the 7.5 cm KwK 40, which differed primarily in using more compact ammunition, thereby allowing more rounds to be carried inside the vehicles. The KwK 40 armed many of the German mid-war tank and tank destroyer designs, replacing the Pak 40 in the latter role.

The Pak 40 may be referred to as the 7.5/L46, referring to it's calibre and the barrel's length in calibres. There were two versions of the KwK 40, which would be referred to as the 7.5/L43 or 7.5/L48.
