This is the second part of a little collection of frame holders for the Prusa I3 MK2 (should fit on the I3 MK1 as well). The collection will at least have the following useful holders:
- Filament guide (http://www.thingiverse.com/thing:2053500)
- LED light holder (this part)
- Spool holder (short and long) http://www.thingiverse.com/thing:2067538
- Camera mount (http://www.thingiverse.com/thing:2067731)
- Filament sensor holder for use with OctoPi
Each of these parts has been designed by different people already and there are many versions available. The idea behind the current collection is to use existing parts where possible and design parts that follow the same design principles (same or similar angles, lengths, same way of mounting to the frame etc.). This gives a much nicer, more homogenous look of the printer.
This LED light holder was once (I think it was designed by gustofusion) on thingiverse and was then deleted. I have completely redesigned the parts, so they comply with my design rules and look similar as compared to the other parts of the collection. For the frame bracket, I have used the original design from the Prusa spool holder. This will be used in all of the parts.
The LED lights itself can be obtained from eBay.

I have connected them to the power supply of the Prusa 3D printer. Since the light are quite bright when running at 12 V, I have inserted a 37 Ohm resistor, so that the get about 9 V. For he future I plan to turn the lights on and off by using Octoprint.
In addition, there is a little hole on the back of the bracket for cable management of the optional LED lights or the filament sensor.
The next parts of the collection will follow in the next couple of days.
