This extendable piston rig captures the classic Minecraft piston design while giving you full control over its mechanical movement. The model is built with clean, block-accurate geometry and organized components, including a static base, a sliding inner arm, and a separate head that extends smoothly along a controlled axis. The rig provides an easy animation controller that allows adjustable extension length, single-step or multi-step motion, and return timing, making it ideal for cutscenes, redstone-style animations, mechanical builds, or interactive sequences. Texturing is handled through simple color-mapped materials consistent with the Minecraft aesthetic, optimized for fast rendering and lightweight use. Exported in FBX and OBJ for universal compatibility.
