MakerBot likes to see their Thingiverse members getting creative solving 3D printing-related problems. To that end, they’ve launched a contest, the Filament Challenge, which encourages 3D designers and printers to come up with solutions for dealing with unruly filament. Create a clever way of storing filament and spools and you could win a 10-pack of MakerBot filament or a one-year membership to MakerBot MakeClub (plus some great discounts and offers). The contest submission deadline is 11:59 PM EDT September 16, 2015. More details on this challenge can be found here: http://3dprint.com/93661/makerbot-challenge/
