In this video we are going to do something a little different. Instead of a typical CAD How-To we are going to look at the design process used for solving a problem. We will talk about about things we should understand like basic material properties and the various mechanisms for storing energy like a rubber band or spring.
This idea came about from a @MarkRober video on making the worlds smallest Nerf Gun.

This video is in no way linked to or Sponsored by Mark Rober, but the topic is interesting and fun trying to solve the challenge.

Since we aren't doing a typical CAD How-To, because the CAD part wasn't complex, here are the files if you want to see or play around with them on your own.

So what other applications could this be used for?
