prusaprinters

<p>Anet A8 comes standard with 20A (240watt) PSU. Upon the stock PSU dying, a 30A (360watt) PSU was purchased to replace: https://www.amazon.com/gp/product/B00D7CWSCG/ref=oh_aui_detailpage_o02_s00?ie=UTF8&amp;psc=1</p> <p>30A PSU does not fit stock frame holes, so a mounting frame was created. Also, had to remix/redesign the switch cover. I took a preexisting cover design (<a href="https://www.thingiverse.com/thing:2320216">https://www.thingiverse.com/thing:2320216</a>) and modeled it to fit the PSU above.</p> <p>Additional Frame Components:</p> <p>3 - M3 nuts - press fit into frame first</p> <p>4 - M3x8mm SHCS - Mounts frame to PSU</p> <p>3 - M3x16mm SHCS or Phillips screws Mounts Frame/PSU combo to Anet Frame</p> <p>Additional Switch Cover Components:</p> <p>2 - M4x8mm Screws to mount cover to side of PSU</p> <p>1 - switch assembly: https://www.amazon.com/gp/product/B00ME5YAPK/ref=oh_aui_detailpage_o08_s02?ie=UTF8&amp;psc=1</p> <h3>Print Settings</h3> <p><strong>Printer:</strong></p> <p>Anet A8</p> <p class="detail-setting rafts"><strong>Rafts: </strong> <div><p>No</p></div> <p><strong>Supports:</strong></p> <p>No</p> <p class="detail-setting resolution"><strong>Resolution: </strong> <div><p>0.2mm</p></div> <p><strong>Infill:</strong></p> <p>40% Zig-Zag</p> <p><br/> <p class="detail-setting notes"><strong>Notes: </strong></p> </p><div><p>Layer Height: 0.2mm<br/> Wall Line Count: 3 <p>Printed in PLA</p> <h3>How I Designed This</h3> <p>Designed in PTC Creo 4.0.</p> <p>3aug2018:</p> <p>Frame Rev 2 - Modified M3 nut to be 5.6mm across for 5.43mm stainless steel nut.
