50mm Extruder Knob with m3 set screw

prusaprinters

<p>I wanted an extruder knob for my Voxelab Aquila that is about the same size as the one on my Ender 3 v2. The original design (<a href="https://www.thingiverse.com/thing:3109769">https://www.thingiverse.com/thing:3109769</a>) is only 40mm in diameter. The Ender 3 v2 has a 50mm knob. So I remixed the original into the same size.</p> <p><strong>**</strong>Update<strong>**</strong><br/> Within a day of using my original design, the flat part of my print's extruder shaft had stripped. This explains why the ender 3 v2's extruder knob comes with a brass insert for meeting the extruder shaft portion.</p> <p>I've updated my design to include an m3 screw that can be tightened against the extruder shaft so that the printed knob doesn't strip off again. The size of the screw I used is an m3x6mm.</p> <p>Thanks to DIY3DTech.com's video for the inspiration: <a href="https://www.youtube.com/watch?v=g7MNkdiRp6E">https://www.youtube.com/watch?v=g7MNkdiRp6E</a></p> <h3> Print Settings</h3> <p><strong>Printer Brand:</strong></p> <p>Creality</p> <p><p class="detail-setting printer"><strong>Printer: </strong> <div><p>Ender 3</p></div><strong>Rafts:</strong></p> <p>No</p> <p><p class="detail-setting supports"><strong>Supports: </strong> <div><p>No</p></div><strong>Resolution:</strong></p> <p>200</p> <p><p class="detail-setting infill"><strong>Infill: </strong> <div><p>20</p></div><br/> <strong>Filament:</strong><br/> MG Chemicals PLA <br/> <p class="detail-setting notes"><strong>Notes: </strong> </p><div><p>0.28 mm layer height<br/> 20% Gyroid infill</p> <p>3 perimeter layers and 3 layers top and bottom</p> <p>no supports</p> </div></p></p></p></p> Category: 3D Printer Parts
