This is an OpenSCAD version of Tanatof's Spool drawer organizer, created to make it adjustable to different spool sizes.
Still working on refinements, so please let me know if the range of size values is too constrictive for your spools.
Still have some other features I want to do, like rounded corners, and a few others.
UPDATE: 2016-01-03 - Added a parameter where you choose to render one drawer or all of the drawers.
UPDATE 2016-01-08 - Thanks for the feedback, esp. from C. Beauregard for pointing out my radius vs. diameter oops. I've uploaded a new file that should generate the correctly sized drawers!
