Ikea Fredde side panel Skadis mount

Here is my first model, a mount for the Skadis to go on the side of the Ikea Fredde desk! supports required The hooks for the desk fit snug so be gentle getting them in. The hooks for the Skadis barely fit, but they fit! Seems to be strong enough, I currently have a shelf for a controller on it and its holding. Any other ideas? Please let me know
