This is my entry for the drawing template contest! 

I made this tool to help draw maps for D&D and other tabletop RPGs. You need one top piece, one bottom piece, and balls to match how dense you want the land mass. Then you add the balls to the bottom, put the top on, shake it, and then take off the top to see your land area.

I marked my paper with a pencil to show where the balls landed and then outlined to create my land mass. You could then add some art and color to make it look like a fantasy map.

You'll want to print this HOT because the bottom wants to fail with all the small gaps. I also added gaps for magnets, but it is too deep. If you have a way to add them without some spacing below them, they'll probably be better for you.
