UPDATE 16/06/13: The making of the acrylic launch buttons/controllers has been interesting, using a piece of 1" Acrylic rod cut 4" long and drilling a hole vertically through it. I will be using 4-wire Telephone extension cables to connect the controller (2 wires for the switch, 2 for an LED so that users can confirm that the controller is plugged in properly).
As you can see here, I kinda messed up the first one
The trick according to my teacher was to go slower.
The next one I did was essentially almost perfect
and the final one was a pain and I broke the drill press at school in the process.
But in the end, I succeeded
Lessons learned: drill slowly (maybe only a couple cm at a time, and allow 5-10 minutes to cool down, don't rush it), if your going to cool it with water, do it from the beginning or don't do it at all, otherwise it separates (as you can see halfway through the second one), never stop the bit inside the acrylic or thats the end of it unless you can pry/spin it off, lastly, it's important to have an emergency stop, that saved my butt more than 4 times on this project.
