Printrbot Simple Metal - Fan Shroud with 5mm LED mount
I found a nice little 5mm LED on Amazon that plugged into my 4pin-molex connectors on the power supply I use to run my bot and wanted a place to mount the bright little bulb. This model is that solution. I found that the official fan shroud that Printrbot supplied was really pretty messy and just wouldn't slice with any settings I used. I went in and rebuilt the shroud (I am no fan shroud guru, I probably messed something up) adding a location for my new LED. I built in support for the LED holder, it printed fine on my bot without any other supports at .2mm layer heights and a 90% fill. I drilled the holes out a bit to make the install run a little smoother.
I used the hole pattern and outside shape and threw the rest away. Original can be found here http://printrbot.com/project/simple-metal/
