Pulley with bearings

prusaprinters

<p>The kids wanted to set up a pulley system across the garden, but the pulleys we bought from the shop were awful, and didn't work at all.</p> <p>I had some bearings in the drawer, so got printing. The pulleys are currently holding up a 40m washing line strung across the garden, and are ratcheted tight between trees, so they can take a good amount of strain on them.</p> <p>The pulleys each need two 608 bearings, two washers, and an M8 nut and bolt. As you can see from the picture, I didn't bother cutting my M8 down, but it makes no difference.</p> <p>Print time for a pair of pulleys is about 4 hours in total on my Prusa i3.</p> <p>Oh, and I've given both the STL and Sketchup files in case you want to make any changes.</p> <p><strong>EDIT</strong></p> <p>The Skethcup file for the outer part of the pulley, when exported to an STL gives erratic results when printed. I used the Netfabb online service to fix it. It printed fine afterwards. Sketchup issues take so long to fix, it's normally quicker to do it this way.</p> <h3>Print Settings</h3> <p><strong>Printer Brand:</strong></p> <p>Prusa</p> <p class="detail-setting printer"><strong>Printer: </strong> <div><p>i3 MK2S</p></div> <p><strong>Rafts:</strong></p> <p>No</p> <p class="detail-setting supports"><strong>Supports: </strong> <div><p>Yes</p></div> <p><strong>Resolution:</strong></p> <p>0.2</p> <p class="detail-setting infill"><strong>Infill: </strong> <div><p>20%</p></div> <p><strong>Filament:</strong> any PLA, ABS &amp; PETG</p> <ul> <li></li> </ul> </p></p></p> Category: 3D Printing
