<p>I recently purchased a replacement Dusk-to-Dawn control switch for my converted gas-light to low-voltage outdoor light assembly.</p> <p>The original photocell light switch model had a much larger eye pattern, and the new design looked out of place. In the photos, I attached a replica of the original design, and a photo of the new design with the much smaller bolt.</p> <p>Current Charm-Lite Design:<br/> <a href="https://www.charm-lite.com/index.php?main_page=product_info&amp;cPath=1&amp;products_id=7">https://www.charm-lite.com/index.php?main\_page=product\_info&amp;cPath=1&amp;products\_id=7</a></p> <h3>Print instructions</h3><h3>Category: Outdoor &amp; Garden Print Settings</h3> <p><strong>Printer Brand:</strong> Prusa<br/> <strong>Printer:</strong> I3 MK3S<br/> <strong>Rafts:</strong> No<br/> <strong>Supports:</strong> No<br/> <strong>Resolution:</strong> .2<br/> <strong>Infill:</strong> 100%<br/> <strong>Filament:</strong> MatterHackers PETG Black Build Series</p> <h3>How I Designed This</h3> <p><strong>Customizer + Meshmixer</strong><br/> I mocked up a couple of simple bolt patterns via Customizer, and then used Meshmixer to pull the two designs into a single bolt. I recycled the retaining nut that was with the original design.</p> <p>Total Length of both designs was 14mm<br/> Nut: M10x1.0x14mm -- added 9/16" hex to aid in loading onto the photocell<br/> Bolt: M21x1.5x14mm -- added 7/8" hex to aid in loading onto the photocell</p> <p>Created with Customizer!<br/> <a href="/apps/customizer/run">https://www.thingiverse.com/apps/customizer/run?thing\_id=193647</a></p> <p>Customizer Values<br/> Using the following options:<br/> type = bolt<br/> head_type = hex<br/> head_diameter = 22.23 ~7/8"<br/> head_height = 6<br/> thread_outer_diameter = 21<br/> thread_step = 1.5<br/> step_shape_degrees = 45<br/> thread_length = 8</p> <p>nut_type = normal<br/> nut_diameter = 14.29 = 9/16"<br/> nut_height = 14<br/> nut_thread_outer_diameter = 10.3 (added some wiggle room)<br/> nut_thread_step = 1<br/> nut_step_shape_degrees = 45</p>
