1. High-quality gear set (self-printed) kit for -extruder extruder, small size, light weight, large transmission ratio, high torque. 2. This gear set is suitable for -LITE-extruder extruder. We provide the X-print file of the extruder. You need to print the printing components yourself (nylon material is recommended). After purchasing this gear set, you can install and use it. 3. High-quality hardened steel nickel-plated gear set, so that you can have more consumables to choose when using 3D printers. 4. At the same time, the larger extruder wheel increases the grip of the consumables and reduces slippage. The larger transmission ratio increases the torque, extruder thrust and printing quality. 5. Increase the torque and concentricity. The hardened steel gear has a larger transmission ratio, increases the torque, and has high concentricity. The production is completed by CNC processing, and the precision is guaranteed.<br><br>Transmission ratio: 9.54647:1 Progress value: 25.12 Pulse: 562 Number of driving gears: 10 Number of reduction gears: 44 Number of extrusion gears: 37 Installation hole position: 2-3.1, neutral distance is 43.5 Supported consumables specification: 1.75mm Due to different batches, there may be differences in product appearance and printed text, which not affect use.
