Yet another lightbar design for the prusa i3 MK3. 

Inspired by this design, though the implementation is original. I tried to make a simpler design which can be printed easily without much support. The OpenScad implementation is included and can therefore be easily modified, but be warned that at stop point I stopped caring and started hardcoding values.

For the hardware I've used this LED strip, this switch, and these fork terminals. For more information about wiring, voltage and where to connect the terminals look at the other lightbar designs which have much better documentation.

For slicing you'll still need supports for the little “tabs” and should use a layer height of 0.2mm.
