Is there a 3D model for wooden pallet I can download and re-size as I need

Hello,
My work requires me to design the pallet for packaging and re-size them as I need too. I have attached picture of what it should look like. I know I can download/draw the pallet and the walls and them assemble them, but I was wondering if somebody has worked something like this.
Greatly appreciate any help in this matter.

Nitish,
Here is side view of the crate. Basically there is pallet as the base and 5 walls around it to protect the shipment and also to make these crates stackable.
What I am looking is a design that I can resize it....I have attached pallet model as well for you to see. I do not know how to add the equation.
