2020 Extrusion Light Bar for 14mm LED strip

thingiverse

I originally remixed this just to accommodate the 14mm wide LED lights I had, but then I thought rather than wire it directly into my control box, I would keep it separate and incorporate a switch so I can control the lights independent to the printer. Since the 2020 extrusion on the Tornado is 400mm wide, I redesigned the light bar to be 200mm long and I printed 2 of them. By the time the printer got to 200mm in height, the light bar was getting pretty wobbly anyway. The end caps are just extended to match the light bar. Because of the increased wattage of my LED lights, I used [18ga hookup wire](https://www.amazon.com/Silicone-Electrical-Conductor-Parallel-Flexible/dp/B07FMRDP87), a [3A power supply](https://www.amazon.com/gp/product/B015FKKGBC), and I used a couple other things to help manage the cabling: * [V-Slot 90 Degree Cable Holder](https://www.thingiverse.com/thing:2001591) * [Cable saddle](https://www.thingiverse.com/thing:4100672) Lastly, I designed the switch box to use [these rocker switches](https://www.amazon.com/gp/product/B07B9RPLZD). The box mounts to the front-right corner of the printer using three T-nuts and the lid is counterbored for three button-head cap screws. (I included bosses inside the box that can be threaded to accept the lid screws). The box and lid can both be printed without support. I chose to print my box as dual color so the front of the box matches the gold color of the printer.
