Formsfield, the high-end 3D printing boutique that opened a few months ago, has announced that they will now give their designers the option to upload items to be made available for free download. Several designers had requested that they be allowed to offer free samples to spur interest in their other work, and Formsfield obliged. To kick off the free service, Formsfield is holding a Winter Challenge from now until January 17. Participants are asked to design useful winter tools and then upload them to the website for free download.
