Ender 3 LED Light Bar

thingiverse

This thing is a 200mm wide LED light bar for the Ender 3 that uses a 24V LED strip and a 24V toggle switch connected to the 24V power supply. I did not have a photo at the time of submitting this thing as I was redesigning the mount and don't have the thing installed at the moment. Note: I have noticed much heat coming from the LED's so I designed this thing to accommodate heat sinks to help dissipate the heat generated by the LED's. I splurged on the toggle switch because I liked the look of it however a cheaper alternative is probably possible as long as it can handle the electrical load. I used two strips of 5mm wide adhesive thermal tape for the 10mm wide LED strip and heat-sinks for adherence as I find that the adhesive that comes on the LED strip is not very good and I already had this thermal tape on hand. There is some electrical wiring and soldering involved so please proceed at your own discretion, ability and risk; I take no responsibility. Incorrect or inadequate wiring could cause a hazard so please be diligent and careful. I am using a Mean Well 350-24 power supply with this design. Some of the parts are small and delicate so please know that you may need to construct this with a bit of finesse and patience. The sequence of assembly can be changed to whatever works for you.
