Choosing Fasteners for 3D Printed Parts – Part 4

Earlier this month, we linked out to the first three posts in the I Heart Robotics team’s ongoing series about choosing hardware for the fused-filament parts that come off your RepRap-type 3D printer. On Sunday, they published the fourth installment, this time focusing on the best way to make a rotating pin joint between two printed beams, for instance in the “knee” of a robot leg. They experiment with various configurations of pop rivets, tubular rivets, flat washers, spring washers, clevis pins, and E-rings. Click through, below, to check out their results.
