X-Belt Tensioner Anet A8

prusaprinters

<p>This is a simple x-belt tensioner for the Anet A8 printer.<br/> I wanted a x-belt tensioner that fulfils following criteria:</p> <ul> <li>G2 geared tooth pulley should fit (the last tensioner I used was too small to accommodate the geared pulleys) </li> <li>pulley should be on the left side of the lead screw, because that design is more stable and needs less G2 timing belt</li> <li>it should be easy to fasten without special tools -&gt; the 3D printed wingnut does a great job</li> <li>it should be easy to print - especially the fastening screw is so crude that it can be printed with a printer that is not very calibrated yet</li> <li><p>it should be stable, simple and robust<br/> I have tried 2 other designs before but they did not quite meet my needs and so I came up with this version. Till now it behaves great and I am quite happy with that design.</p> <p>Credit goes to thingiverse user mike_mattala for his great screw and nut library I used in this project: <a href="https://www.thingiverse.com/thing:193647">https://www.thingiverse.com/thing:193647</a></p> </li> </ul> <h3>Print instructions</h3><h3>Category: 3D Printer Parts Summary</h3> <p>This is a simple x-belt tensioner for the Anet A8 printer.<br/> I wanted a x-belt tensioner that fulfils following criteria:</p> <ul> <li>G2 geared tooth pulley should fit (the last tensioner I used was too small to accommodate the geared pulleys) </li> <li>pulley should be on the left side of the lead screw, because that design is more stable and needs less G2 timing belt</li> <li>it should be easy to fasten without special tools -&gt; the 3D printed wingnut does a great job</li> <li>it should be easy to print - especially the fastening screw is so crude that it can be printed with a printer that is not very calibrated yet</li> <li><p>it should be stable, simple and robust<br/> I have tried 2 other designs before but they did not quite meet my needs and so I came up with this version.
