Cable Holder/Clip for Apple Lightning Cable

I got tired of having to go under my desk to fetch the connector every single time I needed to charge my Apple devices (not to mention my Roomba loves eating those cables).
This is a simple, straight forward design that will take very little plastic to print.
This will fit snug to any 25mm desk and should work with any cable up to 3mm in diameter.
UPDATE: I have slightly modified the design to give it strength and accept desks with different tolerances in their width.
