Bullseye LED Clip

thingiverse

I liked the idea of adding an LED under the Bullseye top part to light up the front of my print. Instead of making a simple angled bracket and gluing it to the bottom, I combined it with the insert for the Bullseye like [Sixteenbit](https://www.thingiverse.com/Sixteenbit/about) suggested, but I wanted a cleaner solution. This design can accommodate an LED strip that is 8 mm wide and about 35 mm in length. It is held in by friction fit, but I will probably modify the design to add ridges that will keep the LEDs in place as well. I wrote a step-by-step guide on how I added the LEDs to my Ender [here](https://ltm56.com/adding-led-lights-to-my-ender-3/)! It should work for other printers too. I also paired it with my [LED light bar](https://www.thingiverse.com/thing:3272248) to have illumination coming down from the top of the printer and make it look nice hiding the wires on the side. These are the things I used to create my lighting setup: [LED Lights](https://smile.amazon.com/gp/product/B013C2U0IO/?tag=ltmtechtv-20) - Cool white at 6k. Very nice to work with. [20 AWG Wire](https://smile.amazon.com/gp/product/B009VCZ4V8/?tag=ltmtechtv-20) - This is way more than you need, but I will be using the rest of it for other projects. Any 20 AWG wire will do, but you need like 10 ft to do the setup that I did. Silicone coated is highly recommended. [20 AWG Silicone JST Connectors](https://smile.amazon.com/gp/product/B071XN7C43/?tag=ltmtechtv-20) - I used these to connect the buck converter to the power supply. I will be posting a guide on how I did this on my website soon. Alternatively, you can also use [XT60 connectors](https://smile.amazon.com/dp/B073QJWVVK/?tag=ltmtechtv-20) or use an [Xt60 splitter](https://www.amazon.com/dp/B0725QDTXY/?tag=ltmtechtv-20) and cut one of the female connectors off to solder to the buck converter if you don't feel comfortable opening up your power supply. [LM2596 DC to DC Buck Converter](https://smile.amazon.com/gp/product/B01GJ0SC2C/?tag=ltmtechtv-20) - converts the 24v from the power supply down to the 12v the LEDs use. [AutoEC 3pc 12V 20A Round Rocker Toggle LED Switch](https://smile.amazon.com/AutoEC-Rocker-Toggle-Switch-Control/dp/B012IJ35VQ/?tag=ltmtechtv-20) - I didn't get these exact ones, but ones like these to add a power switch to the front of my Ender 3. I wired it on the inside of the air duct as shown in picture number 3. I will probably add a little bit of glue on either side for stress relief on the wires and to keep it in place. The print can be printed vertically with supports for a cleaner front look or on the flat face without supports. I have included the STEP file for modification. If you are going to engrave into the design, I would not go more than .5 mm in. That is what I did with mine and it looks decent. (The letters will be painted to give it more of a pop.) If you use Fusion 360, I have also made the [design public](https://a360.co/2qlaptF) for anyone to download.
