A GT2 belt, printed with TPU (thermoplastic polyurethane), that I used in 3D printers to drive the extruder motor, providing a combination of flexibility and strength. With a 2mm pitch, the TPU GT2 belt ensures smooth and precise movement by effectively meshing with pulleys, reducing slippage and enhancing accuracy. Using OpenSCAD, a 3D CAD scripting software, this belt can be designed and customized to fit specific printer requirements. The elasticity of TPU allows for a better grip and durability, GT2 belts for 3D printing applications.
