This is a stand to hold up the [Parallax Propeller Professional Development Board]( http://www.parallax.com/product/32111 ). After propping mine up, just to have it slide down again, I had to made a stand. This stand uses 1/4" wooden dowel to space the left and right sides of the brackets. I found that printing with a raft helped with warping issues. Now you have a nice way to do your Propeller development and demo your prototype in meetings. Print on a raft. Cut two lengths of 1/4" wooden dowel rod to fit your board. I had already put the stick-on feet on my board, so I paced the stand at the very edges. You have several options though!
