Lawnmower Blade Balancer Universal Size

prusaprinters

<p>I wanted to have a blade balancer which fits a wide range of center hole diameters so that I can balance the blades of all different lawn mowers I have.</p> <p>In my opinion the balancing units one can buy are way too expensive so I came up with my own design.</p> <p>The following non-print parts are needed:</p> <p>2x Bearing DIN 6001</p> <p>1x Screw DIN 912 M12x90</p> <p>1X Hex Nut M12</p> <p>6X Magnets Ø20mm</p> <p>6x M4 Screws for Magnets</p> <p>6X Hex Nut M4</p> <p>Print settings:</p> <p>I printed the parts with PETG to achieve a high strength. Especially the base plate (Grundplatte.STL) must be tough. I printed it with 50% infill and 7 perimeters. All parts except Grundplatte.STL print without supports.</p> <p>How to use the balancer:</p> <ol> <li><p>Sharpen lawn mower blade on both sides.</p> </li> <li><p>Put blade on balancer tip. Be sure that the blade is centered. Secure blade with magnets.</p> </li> <li><p>Most likely, one side of the blade is heavier. This side will face downwards.</p> </li> <li><p>Take off the blade and resharpen the heavier side of the blade just a little bit.</p> </li> <li><p>Repeat procedure beginning from step 2 until the blade is balanced out.</p> </li> <li><p>Enjoy your smooth-running lawn mower :)</p> </li> </ol> <h3>Print Settings</h3> <p><strong>Printer:</strong></p> <p>CTC Bizer Dual</p> <p class="detail-setting rafts"><strong>Rafts: </strong> <div><p>No</p></div> <p><strong>Supports:</strong></p> <p>Yes</p> <p class="detail-setting resolution"><strong>Resolution: </strong> <div><p>200</p></div> <p><strong>Infill:</strong></p> <p>50</p> <p><strong>Filament:</strong></p> ERYONE PETG </p></p> Category: Hand Tools
