Recycled Fun Cardboard Cad-A-Pult

The task was to create a something with a green twist. Okay, I'm good with that. A chance to win a Zing Laser cutter for my class is an added bonus. Now if I could add some fun and learning into the mix, it would make it even better.

So what to do? Hmmmm?

My students love to build things and throw stuff so let's put both together! Now, for the green part. Let's see if we can make something that is recyclable and fun! Looking around the classroom, I see lots of cardboard (used shipping boxes) and a good supply of Elmer's glue. So, with a little help from Autodesk's CAD program Inventor, I whipped up a nice little Catapult (Hence "CAD-A-Pult").

Next, to obtain more cardboard, I put out an email to other teachers in my school for boxes. Boy, did the boxes pour in!

If you would like a copy of the plans, information on how to obtain them free of charge is listed after the assembly instructions.

Step 1: An Idea is recycled

A quick jump into Autodesk's CAD program Inventor and the CAD-A-Pult is born. The basic design is set up so that a 1:1 scale drawing will fit perfectly into the Zing Laser Cutter. If we get lucky enough to win the Zing Laser Cutter (hint, hint), we can make a whole class full of these things!

This is really brilliant but the whole point of instructables is telling people how to make stuff, and you're not giving us any plans - upload a pdf of the plans so we can just download them!
