<h3> Unobtrusive Anet A6 X-axis belt tensioner</h3> <p>This is a parametric design for an x axis belt tensioner for the Anet A6 3d printer.<br/> It has been made with FreeCAD 0.17 daily.</p> <p>The design goal was to create a tensioner which requires the least changes to the original printer.</p> <p>You will need:</p> <ul> <li>this design printed</li> <li>an M3 or M4 bolt of about 55mm length with hex head as a tensioning rod</li> <li>an M3 screw cut to 16mm length (including head)</li> <li>M3 nut</li> <li>the two original idler collar bearings</li> <li>a wing nut matching the tensioning bolt</li> <li><p>1.75mm filament of 16mm length for locking the bolt I used a 55mm long M4 bolt, which required me to enlarge a hole from 3mm to 4mm. You could also keep M3 dimensions, but this would require adjusting the "Spannschraube" (tensioning bolt) parameters in the design.<br/> In addition to the tensioning block, there is a bifurcated plate which prevents twisting of the rod-pusher plates when adjusting the tensioning screw.</p> <p>The parametric FreeCAD files (version 0.17 daily) are located at <a href="https://gist.githubusercontent.com/speters/fa7dc90afaea21df740f7c983e6bb5ce/">speters @ GitHubGist / Spanner3.fcstd</a></p> <h3>Print Settings</h3> </li> </ul> <p><strong>Rafts:</strong></p> <p>Doesn't Matter</p> <p><p class="detail-setting supports"><strong>Supports: </strong> <div><p>No</p></div></p> </p> Category: 3D Printer Parts
