Display Light Fixture

My wife teaches at an elementary school, overseeing the Learning Center (Library) and computer lab. This year's theme is "Learning is Our Super Power," which means the entire school has transformed into a world of superheroes and all things related to them. One of the projects my wife worked on was creating a "Kryptonite" display that had to be showcased in a glass case with steel angle iron and diamond plate accents. To bring this project to life, I constructed a wooden base and welded the angle iron together. Next, I designed a custom light fixture to illuminate the kryptonite from beneath using an LED halogen replacement light. My initial design was put to the test, and we observed that even though it was an LED light and not a traditional halogen bulb, it still managed to heat up to around 200 degrees Fahrenheit after about an hour of use. This excessive heat began melting my wife's carefully crafted kryptonite. Given this issue, I decided to redesign the light fixture to incorporate two 30mm cooling fans, one pulling air in and the other pushing it out. The idea was to create a channel where the air would flow across the top of the light using the push/pull fan setup, and then enclose the top with plexiglass for added protection. I also made sure to leave enough space at the bottom for wire management. The revised light fixture has proven to be highly effective, maintaining a temperature below 80 degrees Fahrenheit. To facilitate easy installation, I designed it to be mounted from underneath a fixture, complete with four countersunk screw holes for secure attachment. Additionally, there is ample space beneath the light and cooling fan channels for tucking away excess wiring. A recessed area above the light allows for the mounting of a piece of plexiglass or glass. Here are the components I used to bring this project together: * Luxrite LR21303 7W MR16 LED Bulb, 12V, 50W Halogen Replacement: https://www.amazon.com/gp/product/B01B1PLKYW/ref=oh_aui_detailpage_o08_s00?ie=UTF8&psc=1 * LE DC 12V 2A Power Supply Adapter, AC 100-240V to DC 12V Transformer: https://www.amazon.com/gp/product/B019Q3U72M/ref=oh_aui_detailpage_o08_s01?ie=UTF8&psc=1 * Mini Bi-Pin Socket up to 75 Watts Ceramic Body with Mica Covers for Light Bulbs with Base GU5.3, G4, MR11, MR16: https://www.amazon.com/gp/product/B00DQGL9T6/ref=oh_aui_detailpage_o08_s01?ie=UTF8&psc=1 * 30mm x 30mm x 10mm 3010S 12V 0.13A Brushless DC Cooling Fan DT: http://www.ebay.com/itm/30mm-x-30mm-x-10mm-3010S-12V-0-13A-Brushless-DC-Cooling-Fan-DT-/262452197776?hash=item3d1b5eb990:g:xJgAAOSwNsdXRHtP The 123D Design file and STL file for this project are also included.
