Prusa Mk3 and Mk2 LED Light and Brackets.

thingiverse

I wanted to illuminate the bed on my printer overnight so I could observe what was happening when I popped in randomly on long prints. I found a LED light bar on Amazon and decided to create a bracket around this light. The light is powered by a standard micro-USB cable, which is included, but you have to plug it into a power source. An optional addition is to purchase the micro-USB switch so you can turn the light on/off right next to the light. To install it, you must remove one plastic end cap from the light. Be cautious when doing this as there's a risk of damaging the plug on this end. Worst-case scenario, you can still use the plug on the other end but you won't be able to daisy chain them if you want to. This is a relatively straightforward print and very easy to assemble and install. If you ever need to remove it, simply lift it up and it will pop off like the original spool holder. I designed this so that it wouldn't interfere with printing but still provide light to see what's being printed. It works well with the spool holder designed by MartinMajewski (link below) and my power cable runs through this spool holder for support. If you're looking for a great spool holder for your Prusa, please consider MartinMajewski's design and even submit a tip to him as it's a very good setup, one I enjoy so much that I printed out two for multi-color printing.
