In this video I assemble the key that Adam K6ARK designed and then shared the files so you can print your own. It's a really cleaver design. Below is a link to Adams Printables.com site. It is where you can get the files you need to print and there are links to all the supplies you need.

Adam has lots of great designs.

For mine I just used wire from a piece of CAT5 network cable.
This key has become my favorite.
