Key Hanger

thingiverse

[BlocksCAD](http://www.blockscad3d.com/) is a free online software designed to teach students coding and Computer Aided Design. Using BlocksCAD, students will design a 3D Boat. Using shapes, translate, difference and intersection, students will be exposed to computational thinking to construct something they can 3D print! Note: In order to print a functional Key Hanger, make sure the hook's radius1 is at least 9 mm and radius 2 at least 2 mm. Make sure that the hole for the nail's radii is 2 mm. The Key Hanger Activity is best for 5th - 8th grade for students with basic BlocksCAD experience. As a Teacher you can create a free trial of our [BlocksCAD for Education](https://www.blockscad3d.com/educators/) platform. From here you can create classes with unique join codes and manage student work.
