SummaryThis is a LED bracket for an acrylic frame Prusa i3 that I designed as I couldn't find one anywhere that suited my 3D printer. It bolts to the same M3 screw that triggers the x-axis limit switch. 2 strips of 3, 12V LEDs were cut from a longer strip and attached to the bottom of the bracket. They are wired in parallel and connected to the 12V, 5A terminal of the Ramps 1.4 board; the same way as the fan cooling the board. I have included both the STL and the 123D Design file should you wish to modify it to your liking.
