I received a message suggesting to enter the HaD prize, why not?

According to the rules, the project page must answer the following question :

Why? What would this project solve?

Saying it would help solving the problem of mushroom-shaped-candy-box recycling  would be a bit far-fetched, I don't sure how urgent this problem is.
But hey, at least it would solve my problem, no?

And this project might force me to try 3D printing(something I was thinking about for a while) to solve the problems with my first prototype.

I think this is also the idea behind projects on HaD, some are made to save the world, and other are made just because someone decided it could be done!
