The next step in our Lasertag construction project is the preperation of the boxes for our components. We have decided to put all of the electronics in a backpack. But the backpack will need some I/O. We need a rj-45 for the gun, two for the arm-band, a usb for the key, and a hole for the power switch and power plug. How do we do it? We need square holes… Well, the best and nicest way I can think to do it is to use a little thing called a roto-zip bit. I bought 5 of them at Home Depot for a few dollars. Luckily Karl has a drill press: The pictures mostly speak for themselves. Basically we used a cardstock template:
Then spraypainted the negative:
We will have to use a flat file to make some holes perfect:
But the USB port worked great (It actually looks better in real life)!
I can’t think of a better way to do this in plastic. And the results are nice, with patience and hard work. We have done 10 boxes like this.
