About this 3D model

##This is my take on a printable filament spool. I had a few parameters that I wanted to design to. ###Thanks to Jesse for this great thread. http://www.soliforum.com/topic/3024/reviews-of-printable-spools/ It really helped narrow down what I was setting out to do. * Entirely printable (including center hub) * Interlocking connection in center of hub * Ability to change inside and outside diameter of center of spool seperately * Tapper ability for both inside and outside of hub * Ability to make just spool hubs for pressure fit into tubing (paper towel roll, shipping tubes, toilet paper roll, etc) * low amount of plastic used - (teardrop cutout can be turned on and off) * Filament holes to hold during spooling then to tie loose ends UPDATED: 7/14/13 - Small Fixes to the connectors There are still some options that I want to incorporate but they will have to wait for future designs.
