Adjustable Slop Linear Slides

prusaprinters

<p>My current project involves a precise sliding motion - low friction but also low slop. One way to achieve low slop would be to dial in my printer to the Nth degree and size the parts “just so”, but I took the alternate approach of making a linear slide with integrated tension adjustment.</p><p>So:</p><ol><li>Print out a <code>slide.stl</code> and a <code>slider.stl</code></li><li>Press two nuts into the nut pockets on the bottom of <code>slide.stl</code></li><li>Insert 2x M3x15 bolts into through the holes in the <code>slide.stl</code>&nbsp;</li><li>Place <code>slide.stl</code> into <code>slider.stl</code> . Spray a bit of lithium grease onto the contact surfaces.</li><li>Adjust the tolerance by tightening/loosening the bolts</li></ol><p>It's probably best to print these in a self-lubricating material such as Nylon.</p><p>&nbsp;</p><p>The slider should be modified to hold whatever you want to be able to slide. The model here allows attachment of a M3 bolt to protrude vertically as well as the metal parts of a terminal block (which I used to hold a fretsaw blade).</p>
