The file 'Guitar Stand 3D Printer Model' is (obj,skp,thing,stl) file type, size is 79.8KB.
Here's another guitar stand from 3D Warehouse. Again, I did not make this, I just converted the sketchup file to an .obj. I found it here http://sketchup.google.com/3dwarehouse/details?mid=a10e38ecefff79bfdfd20491defa4a70&prevstart=12
Let me know if this works for you! I haven't tried printing it out yet. Looks ok, might need a little padding adhered to it.
*I updated this with an STL file
