LED strip dimmer switch box for Ender 3

prusaprinters

<p>This is a design for LED strip dimmer for Ender 3 (or any printer with 4040 rail).</p> <p>It has a 2 V-slots and 4 holes for M3 screws with turning nuts.</p> <p>I used a right back hole by enlarging it with a 5 mm drill for cables which then were located in 2040 rail and covered with V-slot covers up to 2020 top rail where LED strip 8 mm wide and 24V was simply inserted and covered with white cover (initially planned with transparent, but white turned out nicely).</p> <p>The lid clicks on the box easily but firmly and leaves a little play for the switch, but not too much to move inside the box.</p> <p>There is also a place in the box for cable management (tight but manageable easily).</p> <p>I connected the switch directly to the motherboard (24V) output, the same which is used for the hot end fan (continuous 24V).</p> <p>The dimmer switch can handle 12-24V so if you use LED strip of 12V with converter, it should also work.</p> <p>Link to the switch I used: <a href="https://www.aliexpress.com/item/32814759066.html?spm=a2g0o.9042311.0.0.27424c4doK0t48">https://www.aliexpress.com/item/32814759066.html?spm=a2g0o.9042311.0.0.27424c4doK0t48</a></p> <p>Link to the COB LED strip: <a href="https://www.aliexpress.com/item/1005003093264495.html?spm=a2g0o.9042311.0.0.27424c4doK0t48">https://www.aliexpress.com/item/1005003093264495.html?spm=a2g0o.9042311.0.0.27424c4doK0t48</a></p> <h3>Print Settings</h3> <p><strong>Printer Brand:</strong></p> <p>Creality</p> <p class="detail-setting printer"><strong>Printer: </strong> <div><p>Ender 3</p></div> <p><strong>Rafts:</strong></p> <p>No</p> <p class="detail-setting supports"><strong>Supports: </strong> <div><p>Yes</p></div> <p><strong>Resolution:</strong></p> <p>0.2</p> <p class="detail-setting infill"><strong>Infill: </strong> <div><p>10%</p></div> <p><strong>Filament:</strong> any PLA black</p> <p><br/> <p class="detail-setting notes"><strong>Notes: </strong></p> </p><div><p>Regular printing position (standing on v-slots).<br/> I used a tree support which was removed very easily. <p>No support for lid, of' course.</p> </p></div></p></p></p> Category: 3D Printer Accessories
