Acrylic Lamp

prusaprinters

<p>This is a fun and easy project that involves electronics, 3D printing and laser/CNC engraving.</p><p><i>Edit July 29 2022: More files and CAD model added with extra guidance</i></p><p><i>This model supports fully open source workflow (FreeCAD, Inkscape or DXF2Gcode, Universal Gcode Sender)</i></p><p><strong>3D printed base:</strong></p><p>The base is designed to fit 3mm acrylic sheet. (+0.1mm clearance in design) 3 different lengths are attached.</p><p>V2.0 is for 15cm acrylic sheet, V2.1 is for 18cm and V2.2 is for 9cm.</p><p>The CAD design was moved to FreeCAD to make it more accessible to everyone. It is fully parametric (see image of the table) so you can create any size for your specific sheet and LEDs.</p><p><strong>Acrylic sheet:</strong></p><p>3mm Acrylic sheet is cut to size.</p><ul><li>using hand tools is no problem, just a bit slow</li><li>when using power tools be careful not to scratch the sheet or melt it with the heat from the blade.</li><li>CO2 lasers can do the cutting for you</li></ul><p><strong>Laser Cutting:</strong></p><p>There are 3 dxf files provided;</p><ul><li>rose pattern</li><li>roadrunner pattern</li><li>Original Lion pattern created by UnpredictableLab which was projected to 2D dxf:</li></ul><p><a href="https://www.thingiverse.com/thing:3107831">https://www.thingiverse.com/thing:3107831</a></p><ul><li>To create your own pattern use canvas feature in Fusion 360 to trace an image.</li><li>There are many sites online that share/sell dxf files</li><li>Open source route:<br>- any image can be processed in Inkscape with “trace bitmap”. Useful laser cutter extensions are “J-tech photonics laser tool” and “KM laser”. See pdf guide for steps.<br>- DXF files for laser cutting work great with DXF2Gcode (I attached the configuration files for my diode laser as an example) See pdf guide for steps.</li></ul><p><i>NOTE: diode lasers cannot engrave transparent things, for that you need to paint the surface black (preferably water colour to wash off when done).</i></p><p>If you don't have access to a laser cutter or CNC you can use a multi-tool (Dremmel) and engrave manually with a printout under the sheet.</p><p><strong>Electronics:</strong></p><p>The base is designed for 9mm wide LED strip that slides in from the side. The strip is powered via USB or battery pack. The USB can be used from any old computer mouse or keyboard. It allows the lamp to be used from both computer port or phone charger as shown in the images.</p><p><i>Note: depending on voltage rating of your LEDs you might need resistors. I used 100 Ohms SMD on the strip.</i></p><p>Have fun printing and building!</p><p>this file was imported from my other profiles (outdated versions):</p><p>myminifactory: <a href="https://www.myminifactory.com/object/3d-print-86572">https://www.myminifactory.com/object/3d-print-86572</a></p><p>thingiverse: <a href="https://www.thingiverse.com/thing:3734480">https://www.thingiverse.com/thing:3734480</a></p><p>&nbsp;</p><h3>Print Settings</h3><p><strong>Printer Brand:</strong></p><p>TEVO</p><p><strong>Printer:&nbsp;</strong></p><p>Tarantula</p><p><strong>Rafts:</strong></p><p>No</p><p><strong>Supports:&nbsp;</strong></p><p>No</p><p><strong>Resolution:</strong></p><p>0.2</p><p><strong>Infill:&nbsp;</strong></p><p>20</p><p><strong>Filament:</strong> rep-rap universe PLA black</p><p>&nbsp;</p><p>&nbsp;</p><p>&nbsp;</p><p>Category: Electronics</p>
