Features: brand new and high quality TL-Smoother can effectively eliminate the mechanical chatter generated by 3D printer motors, especially for parallel arm configurations of the machine effect is significant. Lower vibration lower noise smoother result. Effectively solve the heat dissipation during the use of the module, reduce the hot conditions, and increase the life of the module. Also protected against inductance voltages in the unpowered state of the driver. Eliminate vibration stripes effectively, especially on A4988 DRV8825 etc stepper motor driver we have tested. Specifications: Name: Stepper Motor Driver Filter TL Smoother Filter Size:4x3cm/1.57x1.18in Material:ABS+Metal Weight:40g Note: Due to the problems of lighting effects and shooting angles, there will be certain tolerances in the product, please understand. Please allow 0-1cm error due to the manual measurment. Package includes: 4 Set TL-Smoother
