Micro-servo (SG90) round mounting plate

prusaprinters

<p>I made this mounting plate for a micro servo because my 9G servos didn't have the disc mount which was used in this robot arm model (<a href="https://www.thingiverse.com/thing:1684471">http://www.thingiverse.com/thing:1684471</a>)</p> <p>It fits my "Tower Pro" SG90 micro servos, which have 20 tiny teeth on the shaft.</p> <p>the base of the plate is a bit over 20mm diameter.</p> <p>You need to scale it to fit your printer and currently used filament.</p> <p>Printed on my MK2, they fit with<br/> 95% (tight)<br/> 96% (still tight, but less hard to press on)<br/> 97% just gripping.</p> <p>You can barely see the teeth on the printed part, but they are there, and with the correct scaling work just fine.</p> <p>I only tried PLA.</p> <p>edit: Added freeCAD source file</p> <h3> Print Settings</h3> <p><strong>Printer:</strong></p> <p>Original Prusa I3 MK2</p> <p><p class="detail-setting rafts"><strong>Rafts: </strong> <div><p>No</p></div><strong>Supports:</strong></p> <p>No</p> <p><p class="detail-setting resolution"><strong>Resolution: </strong> <div><p>0.2</p></div><strong>Infill:</strong></p> <p>-</p> <h3> <br/> <p class="detail-setting notes"><strong>Notes: </strong> </p><div><p>Remember to scale for your printer and filament, start with 96%</p></div> How I Designed This</h3> <p>Made with FreeCAD, and abusing the "involute gear helper".<br/> Basically made by the equivalent of bashing something with a hammer until it fits.<br/> Its not pretty, but I'm uploading the freecad file anyway :)</p> </p></p> Category: Robotics
