Y belt tensioner for Graber i3 with F623ZZ bearing

prusaprinters

<p>This is a smaller profile version of the zegmonteiro's "Y Belt Tensioner for RepRap Graber i3". Yes, i still have a graber i3 and it always need some fixing. I tried the original tensioner, but find it to bulky for my printer body. And it never aligned proberly due the larger beagring. I had some spare F623ZZ bearings and decided mix the overall structure of the original tensioner with the x belt tensioner from MazaaFIN's "Smooth X-axis for Prusa i3 with Leadscrews". It worked quite well to me.</p> <p>To use this you will need:</p> <p>2 F623ZZ (3x10x4) flanged bearings</p> <p>2 M3x10 or M3x15 bolts</p> <p>2 M3 nuts</p> <p>1 M4 bolt</p> <p>1 M4 nut</p> <p>3 M3 washes</p> <p>I strongly recommend glue the spare M3 wash on the printer body, right where the bolt point hits, so you dont pierce it over time.</p> <p>Also included, dont know why, is a long cap with space for two M3 nuts and screws. I believe this can be usefull to align the tensioner in case of need.</p> <h3>Print Settings</h3> <p><strong>Printer:</strong></p> <p>Graber i3</p> <p class="detail-setting rafts"><strong>Rafts: </strong> <div><p>No</p></div> <p><strong>Supports:</strong></p> <p>No</p> <p class="detail-setting resolution"><strong>Resolution: </strong> <div><p>1,5</p></div> <p><strong>Infill:</strong></p> <p>i used 30, but 20 or 15 should be ok</p> <p><strong>Filament:</strong></p> n/a abs <p>n/a</p> <p><br/> <p class="detail-setting notes"><strong>Notes: </strong></p> </p><div><p>if you print fast engouth (i printed mine about 60mm/s) you wont need suports</p></div> </p></p> Category: 3D Printer Parts
