Anet A6 Y belt tensioner

<p>This is a remix of <a href="/CH35C0">CH35C0</a>'s <a href="https://www.thingiverse.com/thing:2149867">Y belt tensioner for the A8</a>. The geometry seemed a bit off for my setup and I also wanted to upgrade the idler. This version:</p> <ul> <li>has a lower center for the idler, more similar to the original Anet design</li> <li>has a bigger clearance so that you can fit an idler with guides like <a href="http://amzn.to/2Fz9hbV?tag=revensanchez-20">this one</a>*, which is 18mm in diameter.<br/> <strong>IMPORTANT</strong>: You should install a front panel brace if you plan on using a belt tensioner, like for example <a href="https://www.thingiverse.com/thing:1896013">this one</a>.</li> </ul> <p>This is a snug fit on my A6, you might want to underdimension a tiny bit depending on your printer's accuracy.</p> <p>The idler solves the issue of the light tapping from the belt teeth slipping into the groove of the stock idler and I think teeth might give it more stability. The idler has a 5mm hole, but it works fine with the original 3mm screw. I installed a M5 x 25mm screw, and it fits perfectly and keeps the idler really stable, so I've uploaded a 5mm diameter model as well.</p> <p>I've kept CH35C0's screw and plate intact.</p> <p>*<em> affiliate link if you want to help me out</em></p> <h3>Print instructions</h3><p><strong>Rafts:</strong> No<br/> <strong>Supports:</strong> Yes<br/> <strong>Resolution:</strong> 0.2mm<br/> <strong>Infill:</strong> 40%</p> <p><strong>Notes:</strong></p> <p>Screw and plate should be printed lengthwise if you want the threads to be strongest. However, I went for easy and printed the plate horizontally and the screw standing up. They seem to be able to deal with the torsion fine.</p>
