Keyboard Storage Clips -- Under shelf and behind monitor for Logitech K400, and generic

I wanted under shelf keyboard storage for my HTPC keyboards. I use Logitech K400 keyboards for a couple scattered around the house. After making them I discovered that there were other applications to get keyboards out of the way.

So here are four iterations.

Keyboard clip K400 -- for Logitech compact keyboard K400 with holes for #6 flathead wood screws for under-shelf mount.

Keyboard clip K400-75 -- screw holes moved for attaching to a VESA 75mm mount with 4mm screws.
