**Updated 26 September 2020 A modular, parametric, support free LED strip lamp for your 3d printer, desk, etc. <h3>Changelog:</h3> 26 September 2020: <ul></ul> <li>Added Files:</li> <ul></ul> <li>end_cap.3mf</li> <li>table_mount.3mf</li> <li>connectors_end_cap_and_table_mount_to_straight.3mf</li> <li>theOtherLamp_v1-1.f3d </ul></li> <li>updated Print Settings:</li> <ul></ul> <li>Gap fill</li> <li>Wipe while retracting </ul> </ul></li> <h3>Why I named it the "Other Lamp":</h3> I chose this name in reference to Psalm 119:105 "Your word is a lamp to my feet and a light to my path." (ESV) <h3>Inspiration: <a href="https://www.thingiverse.com/thing:1703104">Led bridge lamp Universal Segment by Opossums</a> </h3> An amazing project that I currently use on my desk, but too large for my printers, and not optimized for printing and easy assembly. So I started from scratch to design a parametric file that produced an simple print that could be easily assembled. <h3>Required hardware:</h3> *optional <ul> <li><a href="https://www.mcmaster.com/91290A115/">M3 x 10mm screw: 4 for each segment and base printed</a></li> <li><a href="https://www.mcmaster.com/97259A101/">M3 square nut: 4 for each segment and base printed</a></li></ul> <li>LED strip (uploaded file supports up to 12.5mm wide x 5mm thick, can be customized to any size in the Fusion 360 file)</li> <li>Power supply</li> <li><a href="https://www.mcmaster.com/9544K22/">*Rubber Feet</a></li> <li>*Dimmer, or smart controller</li> <ul></ul> <li>Reduces heat, prolonging the life of the LEDs and lowers the risk of deforming the plastic if left on for extended periods of time.</li> <li>A couple of different sized bases are included with room to embed various electronics</li> </ul> <li>*Panel mount DC jack</li> </ul> <h3>Features:</h3> <ul> <li>Rigid (no flex when stretching across a long desk)</li> <li>Connected by screws (secure connection that also allows disassembly for easy adaptability to a different space, or for easy transport)</li> <li>Absolutely *0 supports required* (waste of time to remove and can leave ugly scars, and waste of money from the extra filament and print time)</li> <li>Minimum bridging (maximum length is currently across the with of the square nut used)</li> <li>Easily oriented in slicer</li> <li>Custom channel for different sized led strips (would work with rgb, rgb+w, rgb+cct, single color)</li> <li>Gap between the led strip and front of the diffuser to minimize 'spotty' look of the leds</li> <li>Minimum use of filament (save time/money)</li> <li>Space for electronics (I wanted to be able to install a zigbee controller for an rgb+cct led strip for easy home automation or a manual dimmer for a single color led strip)</li> <li>Easy assembly</li> <li>Modular</li> <li>Ability to extend vertically and horizontally</li> <li>Compatible with multiple 3d printing technologies (fdm, sla, etc.)</li> <li>compatible with as many materials as possible (petg, resin, etc.)</li> <li>Scalable (anything from 1/2 foot to 5+ feet)</li> <li>Aesthetically pleasing</li> <li>LEDs extend all the way to table</li> </ul> <h3>Prototypes:</h3> <img height="500" src="https://raw.githubusercontent.com/otherlamp/The-Other-Lamp/master/photos/prototype_1_and_2.jpg" width="375"/> <img height="398" src="https://raw.githubusercontent.com/otherlamp/The-Other-Lamp/master/photos/prototype_3b.jpg" width="500"/> <h3>Print instructions</h3><h3>Materials:</h3> PETG or other higher heat resistant materials. <ul> *PLA is not recommended. It would run the risk of deforming under heat of the LED strip in the diffuser, or any electronics used in the base.</ul> <h3>What to print:</h3> <ul> <li>2 sets of 2_curved_segments_exterior OR 3_curved_segments_exterior. <ul>Choose 2_curved_segments if you want 2 curved pieces on each corner or choose 3_curved_segments if you want 3 curved pieces on each corner.</ul> <li>Any number of the straight_50mm_exterior OR straight_100mm_exterior to reach desired height/width.</li> <li>An equal number of diffusers as exteriors.</li> <li>Connectors. (Notice the small circle to signify that side connects to a curved segment, allows easier identification at a glance.)<img height="456" src="https://raw.githubusercontent.com/otherlamp/The-Other-Lamp/master/assembly/connectors.jpg" width="500"/></li> <ul> <li>connectors_curved_to_curved connects curved segments.</li> <li>connectors_straight_to_curved connects curved segments to straight segments. <li>connectors_straight_to_straight connects two straight segments.</li> </li></ul> <li>For large base:</li> <ul><li>base_large_exterior</li> <li>base_large_diffuser</li> <li>base_large_floor_with_bumper_cutouts OR base_large_floor_without_bumper_cutouts</li> <ul><li>Use the file with the bumper cutouts if you want to use the bumpers I linked above. If you don't want bumpers or want to use adhesive bumpers use the file without the bumper cutouts.</li></ul></ul> <li>For small base:</li> <ul><li>base_small_exterior</li> <li>base_small_diffuser</li> <li>base_small_floor_with_bumper_cutouts OR base_small_floor_without_bumper_cutouts</li> <ul><li>Use the file with the bumper cutouts if you want to use the bumpers I linked above. If you don't want bumpers or want to use adhesive bumpers use the file without the bumper cutouts.</li></ul></ul> <li>For table mount: If you want to mount it to a table with electronics hidden under the table. <ul> <li>table_mount </li></ul> <li>If you only want to print a vertical piece, or half an arch, etc.: <ul><li>end_cap</li></ul> </li></li></li></ul> <h3>Print settings:</h3> <ul> <li>Supports: NONE (!!!)</li> <li>Nozzle size: .4mm</li> <li>Elephant foot compensation: 0.2</li> <li>Brim:</li> <ul><li>Exterior/Diffuser/Base: Disabled (0mm)</li> <ul>There is a built in brim on the interior of the pieces, reducing the risk of scarring the visible parts of the print. </ul> <li>Connectors/Floor: Optional</li> </ul> <li>Perimeters: 3</li> <ul>As there is more overhang on the top half of the curved segments it will require some infill. Increasing the perimeters will replace the infill with 'Gap fill'. (The rapid back and forth of the infill can cause a little bit of wobble on the print, decreasing some of the print quality)</ul> <li>Wipe while retracting (Printer Settings>Extruder): disabled <ul>When printing the 45° overhang on the exterior windows the plastic would curl just enough to catch on the nozzle during the wipe, and due to the small surface area on the build plate pulled a few of my prints off the build plate. Disabling the wipe prevented this.</ul> <li>Extrusion Width and Overlap (These are the default settings for Mk3s. Ensures that the exterior is exactly 4 perimeters, and the diffuser is exactly 2 perimeters)</li> <ul> <li>Perimeters: .45mm</li> <li>Infill/Perimeters overlap: 25%</li> </ul> <li>You can customize openings by adjusting/adding/removing the included modifier on the base. (keep in mind the height of the lip on the floor of the base) Required modifiers:</li> <ul> <li>(Infill) Fill density: 0%</li> <li>(Layers and Perimeters) Bottom solid layers: 0</li> <li>(Layers and Perimeters) Perimeters: 0</li> <li>(Layers and Perimeters) Top solid layers: 0</li> </ul> <img alt="Buddy" height="320" src="https://media.prusaprinters.org/thumbs/inside/1280x960/media/prints/39222/images/387843_c5890ae4-4502-46e1-9e22-9ee3d9d47731/modifier-example.jpg" width="500"/> <li>It may require some experimenting to get your preferred transparency of the diffuser, and may change depending on filament. You can do the exact opposite of everything recommended <a href="https://blog.prusaprinters.org/3d-printed-lens-and-other-transparent-objects_31231/">here</a>. (You want to decrease transparency, while the article tells you how to increase it.) These are the settings I currently use: <ul> <li>(Speed)Gap fill: 0mm/s</li> <ul>The 'gap fill' is visible in the diffuser (and possibly in the exterior pieces if using a semi-transparent filament)</ul> <li>(Speed)Perimeters: 30mm/s</li> <li>(Speed)Small perimeters: 30mm/s</li> <li>(Speed)External perimeters: 30mm/s</li> <li>(Filament > Cooling) Min print speed: 30mm/s</li> <li>(Extruder temp) 240 C</li> </ul> <figure class="media"> <oembed url="https://www.youtube.com/embed/NfZZVUIxqhk"></oembed> </figure> <figure class="media"> <oembed url="https://www.youtube.com/embed/sEXhBJ90o-U"></oembed> </figure> </ul> <h3>Assembly:</h3> <ol><li>Print pieces and gather hardware.</li></ol> <ul><img height="375" src="https://raw.githubusercontent.com/otherlamp/The-Other-Lamp/master/assembly/resized_assembly-1.jpg" width="500"/></ul></li> <li>Slide 'Diffusers' into 'Exteriors'.</li> <ul><img height="375" src="https://raw.githubusercontent.com/otherlamp/The-Other-Lamp/master/assembly/resized_assembly-2.jpg" width="500"/></ul></li> <li>Place nut into one of the channels in the connectors.</li> <ul><img height="375" src="https://raw.githubusercontent.com/otherlamp/The-Other-Lamp/master/assembly/resized_assembly-3.jpg" width="500"/></ul></li> <li>Secure the connectors to one of the segments with the screws.</li> <ul><img height="375" src="https://raw.githubusercontent.com/otherlamp/The-Other-Lamp/master/assembly/resized_assembly-4.jpg" width="500"/></ul></li> <li>Place nut into the other channel of the connector</li> <ul><img height="375" src="https://raw.githubusercontent.com/otherlamp/The-Other-Lamp/master/assembly/resized_assembly-5.jpg" width="500"/></ul></li> <li>Slide next segment over connectors and secure with screws.</li> <ul><img height="375" src="https://raw.githubusercontent.com/otherlamp/The-Other-Lamp/master/assembly/resized_assembly-finished.jpg" width="500"/></ul></li> </ol> LEDs can be fed through the channel in diffuser as you assemble it. <h5>Assembly Video:</h5> <figure class="media"> <oembed url="https://www.youtube.com/embed/zav5JRe_224"></oembed> </figure> <table border="1" cellpadding="8"> </table> <h3>Additional Resources:</h3> <ul></ul> <li>I am currently working on documenting all 60(ish) parameters in the .f3d file.
