This is a derivative of: http://www.thingiverse.com/thing:4337 by randyyThere were several things I didn't like about this. The first is the spool was too small, so my filament would just unwind itself. The second was that I didn't have any rods to go between the spools. Finally, the hole in the middle was too small for the rod I wanted to but it on.So what did I do? Made it extend-able, so the size of the spool can be changed. Made the center hole bigger. Made it so I could attached printable hooks to hold the plastic onto the spool (and made them double, so that it would hold more plastic!)AND, to save myself some plastic, I made the ends with connectors so you can attach them and hopefully get more plastic onto less spools.Print 2 spools (1 center piece, 6 arms) Print 3 spool ends.Spool ends go through and then hook onto the arms.Try hooking things up in different ways, maybe you can get 4 rolls of plastic on only 2 or 3 spools! Very configurable.NOTE: Fix_Catch.stl is to slide onto ends that arnt hooked onto the spool, so that the plastic doesn't catch (Ex. I have 4 spools printed, but I have 6 spools spots for plastic, so I need a few of these for the empty spots)
