Here's a chance for you to get your greedy paws on something cool for free:
Readymechs are flatpack toys that can be printed out on 8.5" x 11" sheets and constructed by you...for free! All you need is double-stick tape, thick matte paper, and 10-15 minutes for build time.
Okay, okay, so the tape, paper, printer ink, and printer cost money...and time is money, but these sweet designs brought to you by FWIS, a graphic design group in Portland, Denver, and Brooklyn, are more than worth the expenses. Try and "collect" all 22.
