MicroBeltTensioner (Customizable)
prusaprinters
<p>This is a very small and customizable belt tensioner with a very low profile on the belt movement.</p> <p>By default the lost belt movement is about 23mm using a M3 screw and nut. However since this is customizable you can shrink it even more if you like. Same if you like the design and want a bigger more robust tensioner or more space for a bigger belt.</p> <p>When using the default objects you need a M3 nut and a M3 10mm screw. Embed the nut into the matching hole and place the clamp over it. Now put in the screw from the other side. The belt goes in from the screw side, around the clamp and back to the side with the screw. The non teeth side of the belt should be facing outwards for optimal results and minimal stress on the belt itself.</p> <p>By turning the screw the clamp will press against the clamp and push the belt outwards.</p> <p>I used them on my TronXY X5 to tension the X and both Y belts. If printed right this tensioner is strong like hell.</p> <p>FreeCAD source for customization is as always included.</p> <p>Happy Printing</p> <h3> Print Settings</h3> <p><strong>Printer:</strong></p> <p>Tronxy X5</p> <p><p class="detail-setting rafts"><strong>Rafts: </strong> <div><p>No</p></div><strong>Supports:</strong></p> <p>No</p> <p><p class="detail-setting resolution"><strong>Resolution: </strong> <div><p>0.2</p></div><strong>Infill:</strong></p> <p>42%</p> <p><strong>Filament:</strong> Janbex PLA, ABS Black <br/> <p class="detail-setting notes"><strong>Notes: </strong> </p><div><p>Print with a brim, if you have issues with the bed adhesion.</p> Also print with four walls for additional strength. For the main part rotate it, so that the nut pocket it facing upwards. The clamp should be printed with both legs on the side, so the layers increase the parts strength.</div></p> <p>If possible try to print with ABS to get the most robust tensioner. However, I used PLA parts for over 300 printing hours without any issues. The only broken piece was one of the early test prints with only two outside walls and even that part worked for over 100 hours.</p> </p></p> Category: 3D Printer Parts
