What if gunpowder had never been invented? In this alternate timeline, cannons never replaced mechanical siege weapons. Instead, engineers kept improving catapults and other siege machines. For this remix, I turned the original T-34 into a mobile siege vehicle inspired by Leonardo da Vinci's designs while keeping the original magnetic modular system. This model was created for the T-34 Evolution Remix Challenge hosted by Bavaria_3D Tanks. What was remixed? Starting with the original modular T-34 platform, I designed a completely new siege module and added several medieval-inspired parts. New Components Fully functional mechanical catapult Wooden front shield Wooden side armor panels Side mounting beams with hanging chains Wooden loading platform Rear storage crate Basket with removable stone projectiles Side ladder Front assault ram The original magnetic mounting system has been preserved, so the complete siege module mounts to the T-34 chassis just like the original turret. Printing & Assembly Optimized for FDM printing. Most parts can be printed without supports. The catapult is assembled using both printed pins and short pieces of 1.75 mm filament. A small piece of string is required for the catapult mechanism. One standard rubber band is required for the trigger mechanism. Stone projectiles are printed separately and stored in the rear basket. Fully compatible with the original Bavaria_3D Tanks magnetic T-34 platform. Design Story I wanted to imagine how the T-34 might have looked in a world where mechanical siege weapons continued to evolve instead of firearms. The result is a mobile siege machine with a functional catapult and medieval-inspired equipment, while still keeping the original modular T-34 platform. Safety Notice Although this is a toy model, always use it responsibly. Never aim or launch projectiles at people or animals. Use only the included printed stone projectiles and operate the catapult in a safe, open area. Original Modular T-34 Platform by
