PLA tested Spring / Shock system Suspension

I know it is closer to a spring then a shock system but it does the trick. I was trying to learn Inventor LT and I came up with this design. I wanted to know if PLA could function as a printable spring/shock assembly and it worked well.

This is designed to be a concept only so this lacks a finished assembly or mounting points.. I suspect you can add these. Please use this and share with me what you do with it. I'd love to see what this goes on to influence. I tried to find a similar thing on
