Prusa i3 Rod-Mounted X Tensioner

prusaprinters

<p>This is a simple adjustable belt tensioner that mounts on the top rod on the right end of the X gantry.</p><p><a href="http://www.youtube.com/watch?v=u8CJW0iWXlo">See it in action…</a></p><h3>Instructions</h3><p>For an adjustable tensioner you need to add a 624 bearing, a 4mm screw, and a 3mm screw to this part. It's designed for mounting on the top rod on the right end of the X gantry. Of course your x axis needs to be set up so the bottom span of the belt attaches to the x carriage. This tensioner will probably work fine inverted on the bottom rod too.</p><p>The parametric SCAD file also allows you to print a non-adjustable part at your adjusted tension. A sample non-adjustable one is included in this Thing. You can also adjust other parameters, such as wall thickness, bearing screw size, etc.</p><p><strong>Try the </strong><a href="https://www.thingiverse.com/thing:554719"><strong>Prusa i3 Add-On X Tensioner</strong></a><strong> as an alternative!</strong></p><p>&nbsp;</p>
