Lights for your Prusa! Powered by the printer, small and out of the way, and very bright. Just place these holders on top of your Z-axis caps, insert some wires, and pop the lights in. These holders use 42mm "Festoon" LED bulbs, available at the link below. These particular bulbs can operate at both 12V and 24V, so they are compatible with all Prusa printers.
Wire these lights in parallel. I'd also suggest securing the holders with zip ties once you're happy with your setup.
Print these parts with the bulb clips facing upward (with one end of the large cord hole on the print bed). I suggest using a brim because the area contacting the bed is quite small. You will need supports for the hexagon feature.
