NOTE: THIS ITEM IS NOW DEPRECATED. Please surf on over to version 2. Thanks.This is a OpenSCAD file for making a spool holder out of a Lazy Susan bearing. The tri-slot middle is so that you can fit multiple custom spool adapters if you swap between different brands of filaments. I'd decided to design this after reading an Instructible about using a Target Lazy Susan spice tray as a spool holder... http://www.instructables.com/id/The-10-10-minute-Filament-Holder/ Unfortunately I ran into (and thought of) a few problems: However, the current stl on this "thing" is for a 4-inch bearing purchased at ACE Hardware. It cost me around $5 and it was in stock at a store near my workplace. http://www.acehardware.com/product/index.jsp?productId=3463597 With ABS I had to scale by 1% (1.01 multiplier) because of shrinkage. (TODO: Due to the difficulty of making this align with the bearing, I need to re-release this again with a slotted screw hole for "fudging" the tolerances. Note: Carefully rotate/align the nut traps.) The screws and nuts are typical m4 hardware. The .scad file is provided for you to customize for your spools and bearings! I highly recommend AGAINST printing these pre-compiled stls!More detailed instructions soon....
