K8200 SnapIn Hook 15mm

I use a few tools together with my printer all the time. These are Allen hex keys, electronic calipers and a USB adapter for microSD cards.
I decided to make holders for the tools that are printable in PLA and snaps in place without the need for screws.
This particular thing is a hook that I use for the fat end of my electronic calipers. It should be just over 15 mm wide when printed.

The hook for the thin end is found at http://www.thingiverse.com/thing:517220
