Ender 3 Pro Belt Tensioners

thingiverse

This was designed for the Ender 3 Pro and inspired by similar models out there, but as an engineer, I couldn't just reuse someone else's and had to make my own. I had originally designed the adjustments to be done using a separate key to keep the size down during normal times, but after using it, I have found I can turn the knobs with any additional leverage that the key provides. The Y-axis tensioner will not work with a normal Ender 3, as the Pro uses a different sized extrusion for the Y-axis. It will reuse the stock hardware for and Ender 3 Pro. The X-axis tensioner should work on both Ender 3 Pro and Ender 3, although I have not tested this on an Ender 3, so use at your own risk. I did need to buy a m8 bolt and nut to use with the X-axis tensioner on my Ender 3 Pro, but I believe for the Ender 3 you can reuse the stock hardware All of my designs are unpaid passion projects that I choose to share, and I provide mesh models for free, but if you'd like to support me and my work, donations are greatly appreciated.
