ThinkFun Nut & Bolts

thingiverse

UPDATE Oct 1, 2015: Bolt-Meets-Nut-Perfectly printed in ABS snaps onto nut flawlessly. Nut-Stick-To-Bolt-Tighter fits securely with factory M8 bolt if your filament has some shrinking capabilities or you can print the older Bolt.stl and nut pair instead. These parts were crafted to sabotage the concept of a hassle-free plug-and-play construction set, pushing kids to think critically like engineers from an early age. The first phase of my cunning plan revolves around bolts and nuts. PS: In reality, original parts refused to cooperate because I made the critical mistake of printing them in ABS which caused tiny holes to shrink excessively.
