Tensionatore per asse Y per Ender 3

Using this Original Creality tensioner module, you now can adjust the tension on your Ender3's Y-axis timing belt with ease. Fits on 20x40 aluminum frames, so can be fitted on other printers as well. By making sure the tension on the belts is perfect, your 3D prints will look better, reducing 'ghosting' and layer offsets.
