Print-in-place carabiner

Project Description

I designed this carabiner while learning about support types in my mechanics class. I wanted to design a 3D-printable hinge/pin that could be printed in place as one 3D print. The culmination of my experimentation with print-in-place hinge designs was this carabiner I designed in Solidworks. It utilizes a precisely determined air gap between the moving parts of the hinge to allow for a tight but movable latch. 

After printing the carabiner on my modded Wanhao Duplicator i3 V2, it worked as intended. Future plans for this project include designing a locking mechanism for the latch of the carabiner and improving the aesthetics and overall designs of the model.
