Using this light some details and areas may still be hard to see, like directly under the nozzle, but I designed it for checking on prints. Either checking in person or via the webcam it provides plenty of light, without leaving the main light on, to make sure I haven't been attacked by the spaghetti monster.

Here is a link for the light I used in this design. I'm sure it would work with others, but was specifically designed for this one (link as of 1/15/17).

I uploaded the lid for the switch box as well as the complete file in case you have tolerance issues, you can scale and re-print just the lid as needed. I did not
include wire holes in the switch box so it could be adapted and placed wherever someone wants. For this particular light, use a 5/32 drill bit to drill the holes.

The nut hole in the brakets is designed for a hex nut, as it's what I had available, but should work with a square nut as well. They may just be a bit more loose until tightened. The screw needed should have a threaded section of 6mm or shorter. The screws I used were 6 mm in total length, 5mm threaded.

I wired directly off the MK3 24v psu for this. As indicated by the product description, it will also work on 12v power supply.
