Spool Holder/Dispenser Castle tops

These parts upgrade your Spool Holder/Dispenser http://www.thingiverse.com/thing:74050 it raises your spools up enough for your wires to clear. The spool-supports evens out the odd sized holes of your spools and keeps them spinning freely. This upgrade allows you to use a 1/2" rod or tubing instead of the all-thread, eliminating your spools from walking. I have about 20hr of trouble free printing with this modification.
