timing belt tensioner on dual z axis (with idler)
prusaprinters
---Made for ender 3 v2, but you could use it on other ender as well---What is this? Its an timingbelt-tensioner for the dual z-axis on the ender 3, because they tend to skip e-steps. Thus one side is higher or lower, creating a misalignment on the printer x axis. The tensioner does keep the belt tight so the axis are in synch. Info:This model was created because the aliexpress seller wrote its suitable for the ender 3, but it isnt for the ender 3 V2! So I created this model, as seen on the first picture as a reference the black original part V.S. mine printed in red.
