So my wife is a volleyball coach and she is usually the first person in the gym every morning. Unfortunately the lights in their gym (and most gyms) require a key to turn them on and since she was not issued one by her school I decided to make her one. This key is made to go on any key ring and should work on most gym lights or any lights that are similar.
Also my wife tends to lose things quite frequently so I made this key extra large. If you would like me to down size this key please leave a comment and a can whip something up real fast in Inventor.
To ensure strength, print at 100% infill. This print takes around 10 minutes to complete (at least on my Aluminum Mendel).
I also included the GCODE so you can just download and print.
