The team at Creative Tools, a Swedish reseller of 3D printing hardware and software, have gone the extra mile to help make your 3D printing experience more effective and enjoyable by making an entirely 3D printable filament spool holder. It works with the vast majority of filaments and filament spools, and the parts are all available as a free download on Thingiverse. Also very cool? The filament spool holder doesn't require the use of nuts, bolts or fasteners. You can read the whole story here: http://3dprint.com/33834/creative-to...lament-holder/
