About this 3D model
Ok, here's the last guitar stand I found at the 3D Warehouse. Or, at least the last short one. You could get adventurous and try to make a taller one, maybe get some metal rods. Let me know if it works out for you! I didn't make this, I found it here http://sketchup.google.com/3dwarehouse/details?mid=160a062606a26a72d981363083272c7&prevstart=12 *I updated this with an STL file.
