Wire shelving hooks and hangers

Update: Added a "tool holder" for the large wire shelves. I'm using them for pliers, safety goggles and screwdrivers. Please leave a comment if you want other brackets or other shelf sizes.

##Handy hangers
This project actually grew from some curtain rod hangers for wire shelving.
To warm up for that project, I created simple parametric hooks and hangers in Fusion 360.
This warm-up project took on a life of its own and has proven popular with my social media followers.

These are quick to print and super-handy.

Please comment with your experiences and we'll get STLs for other sizes posted.

##Files included:
This post includes 2 styles in 4 shelf sizes.
The name of each STL includes the total height of the shelf it is designed for.
See the "Parametric!" section below for more information on how these are sized for different shelves.

There is also a public link in that section to the Fusion 360 project.
