I found this fantastic tutorial by Kris Compas, it's a 1 inch scale version but you can easily convert it to work in any scale. I'd love to make one for my MSD size :)
If you've got some mat board, card stock and a couple small dowels laying around - you can make this too!
I am posting a direct link as it's quite detailed, but looks easy enough that even I could do it.
Check it out and if you make one, I'd love to see a pic!
