This is a project that I have been working on for some time. I sincerely hope you enjoyed it. ( :

WARNING: DO NOT look into the LED at close range when powered, it has the power to burn through your retina in seconds.

If you plan to make this, there are few things to remember;
1. depending on the parts you bought, my design may not fit perfectly.
2. you may need to drill a few holes here and there, especially when mounting the battery compartment.
3. The fan needs to be overvolted slightly to keep the LED cool, alternatively, you may use a 50W LED, and set the current to 1.5A, everything else remains the same.
4. You MUST print the Parts beyond the voltage booster in ABS or other higher temperature plastic. PLA will melt.
