Swivel Brake for Office Chair

prusaprinters

<p>I designed this so that I could use my flight simulation rudder pedals without my office chair swiveling.</p> <p>To engage the brake, I use the lever built into the chair to lower the seat onto the printed column. There's grippy stuff on the bottom of the seat and the top of the column to prevent swiveling, because the lugs engage the base of the chair.</p> <p>The gas strut is still there, so you can stand up and reposition if you need to, and then you can just hit the lever to raise the seat up to "office mode" and swivel works great.</p> <p>It's designed for an Autonomous office chair, but it should work OK for anything with five legs. (Maybe some zip ties?)</p> <p>I initially designed it to have a PVC outer and inner column, but wound up making it a unitized one-piece assembly. If you want to sit taller, it'd be easy to modify this design or print out some circular shims.</p> <h3>Print instructions</h3><h3>Print Settings</h3> <p><strong>Printer Brand:</strong></p> <p>Prusa</p> <p><p class="detail-setting printer"><strong>Printer: </strong> <div><p>I3 MK3S</p>&lt;/div&gt;<strong>Rafts:</strong></div></p> <p>Doesn't Matter</p> <p><p class="detail-setting supports"><strong>Supports: </strong> <div><p>No</p>&lt;/div&gt;</div></p> <p><strong>Notes:</strong></p> <p>Print with four or five perimeters. I'm a big boy, and it's pretty sturdy, but don't skimp.</p> <h3> Post-Printing</h3> <p><strong>Add grip material to prevent chair swiveling</strong></p> <p><div><p><a href="https://www.lowes.com/pd/Scotch-Grippy-Dot-Pad/1002690314" rel="nofollow">https://www.lowes.com/pd/Scotch-Grippy-Dot-Pad/1002690314</a></p> I trimmed this to fit the top of the cylinder, and also put some on the bottom of the chair (around the chrome gas strut). This will prevent the chair from swiveling when you lower it.</div></p></p></p>
