My goal was to create a simple way to mount the speakers on the side of the desk such that they don't take up space on the desk and do not fall.
This model introduces a base attaching to the speakers with screws and a tapered shaft attaching to the speaker to the mount and allowing rotation.
I screwed the mount to the side of the desk plate with long screws.
 

Required hardware:

• 4x 10mm M5 cap screws

• 4x Screws for mounting to side of your desk
