first thing ever made so this is mostly a test. everything should be within a mm so if this works it should be functional but i have not tested it.
edit 2* fixed the hole and the file is now a solid. Also attached the google sketchup file for anyone that wants to edit.
edit* looking at the image it looks like one of the hole is not all the way through. Was not exported like that so i dont know how to fix it. just poke it the rest of the way through i guess :S
Modeled in mm so import in mm.
