Lightbars 4.0 for extrusion based 3d printers

thingiverse

This project is a significant upgrade to my previous lightbar work, extending its edges for more comfortable printing with a printer at eye level. It introduces two new sizes (200mm and 100mm) compatible with smaller print beds and printers, as well as a fully enclosed lightbar mount that conceals wires from the lightbar to the frame edges. Additionally, it features my corner reinforcement covers, designed for Taz printers but adaptable to square 20mm extrusion designs, aiding wire routing from extrusions to control box areas. Update 1: New 4.5 variant endcaps and mounts now allow for easier wire routing with larger sizes. Print Settings: Printer Brand: LulzBot Printer: TAZ 5 Rafts: No Supports: No Resolution: 0.5mm nozzle, 0.3mm layer heights Infill: 85% Notes: To print the longest bar, a Taz or similar printer is required, and diagonal printing on the bed is necessary. Post-Printing Instructions: Insert the slot covers into the t-slot that will become your cable run, typically the top bar and one side bar. Consider purchasing extra for aesthetic purposes even if not planning to route wires in that side. Determine end mount locations and punch a hole large enough to pass positive and negative wires through the surface of the slot cover at that point. Print all parts. Begin assembly by attaching a 12 or 24v, 5mm wide "waterproof" light strip, which has its own built-in lens. Drill a hole in the center of the endcap for wire routing (a 1/8" drillbit should fit). Adhere the light strip to the light bar and press both endcaps onto it. Carefully feed wires through the enclosed mounting ends. You will have wire protruding from the section that will be in contact with the extrusion slot cover. Feed the wire through the hole and over to the corner. Optional: Install one of the corner slot cover pieces for additional space to conceal wire quick disconnects and pass the wire from the top extrusion into another extrusion slot cover on the side, then down into the control box.
