The Panther Ausf. A (Sd.Kfz. 171) was one of the most significant German medium tanks. It was developed during World War II in response to encounters with the modern Soviet T-34 and KV-1 tanks on the Eastern Front in 1941. Development of the new tank began in late 1941, and serial production of the first Panther Ausf. D variant started in 1943. The Ausf. A variant was produced from August 1943 to May 1944 and introduced a number of improvements over its predecessor. The Panther's design was largely based on knowledge gained from studying captured Soviet T-34 tanks. The Germans adopted, in particular, the concept of sloped armor, which significantly increased protection without requiring thicker armor plates. At the same time, the Panther incorporated proven elements of German tank engineering, such as an advanced torsion bar suspension system and high-quality optics. The main armament consisted of the 75 mm KwK 42 L/70 cannon with a high muzzle velocity, capable of destroying most Allied tanks at long range. Secondary armament was provided by two 7.92 mm MG 34 machine guns. The crew consisted of five men – the commander, gunner, loader, driver, and radio operator. The Panther Ausf. A was deployed primarily on both the Eastern and Western Fronts, where it excelled in firing accuracy, excellent cross-country mobility, and highly effective frontal armor protection. Although its complex design placed greater demands on production and maintenance, it became one of the most respected armored fighting vehicles of World War II. Today, the Panther Ausf. A is regarded as one of the finest tanks of World War II and remains one of the most popular subjects among collectors, scale model enthusiasts, and military historians. This 1:10 scale tank kit is primarily designed for radio-controlled operation. However, it can also be built as a static display model. The STL files are designed to provide a highly detailed and realistic build for military vehicle enthusiasts. The construction has been engineered for precise and straightforward assembly using an interlocking system—most components are secured with screws and adhesive, ensuring exceptional structural strength. The upper hull can be easily removed, providing convenient access to the electronics, simplifying maintenance, and making future repairs easier. The model can optionally be upgraded with a wide range of additional features, including an airsoft firing mechanism, gun recoil, a functional exhaust with smoke effect, or a sound module. The printable files are optimized for home 3D printers, with a strong emphasis on easy printing and straightforward assembly. Main Features of the Panther Ausf.

Delivery Time: Usually immediately, but no later than 24 hours after payment is received Notes: * Assembly of the model requires precision and previous modeling experience. * The purchase includes digital files for 3D printing only. * This model is not an exact replica or scale reproduction of the original combat vehicle; therefore, some details and dimensions may differ slightly from the real vehicle. 1) The Panther Ausf. A model was designed with a strong emphasis on detail. However, it is not an exact replica or scale reproduction of the original vehicle, and some details or dimensions may differ slightly from the real tank. 2) The model can also be printed on a printer with a smaller print bed (<220 mm), but some parts must first be split in the slicer using the cut function. Several larger components have already been designed to fit printers with a 220 × 220 mm print bed. The optimal print bed size is 256 × 256 mm. 3) See the publicly available assembly manual linked in the product description.
