Light bar mounts

thingiverse

You can use two (or more) of these to hang [these light bars](https://www.amazon.com/gp/product/B06XZ6V3NM/) on your Ender 3. Three light bars are supplied, along with cables and a power supply, so you won't have to tap into your printer's power supply. I note that today the light bars indicate they're out of stock; however, if you take a closer look at the Amazon page, you'll see other vendors who have them in stock. The light bars come in sets of three (or more, depending on where you shop), but you can use any number based on the capacity of your power supply. They simply daisy chain their power. For the Ender 3, placing one in front and one at the back provides excellent lighting for the print bed. The light bars are quite sturdy, and securing them just takes a couple of mounts. The mounts slide into the sides of the top support; all you have to do is remove the plastic cap, slide the mounts in, put the cap back on, slide the light bar into the mounts, and you're done. Alternatively, you can attach the mounts to the light bar first, then slide them into the top support - either way works just fine. In this design, the light bar channel width is 25mm, and the notch on the sides is 2mm high with a maximum retaining incursion of .5mm at the beginning of the slope as it widens outwards.
