I made this model in Fusion to hold my cheap device switcher kvm from ebay on top of the hp usb c docking station i use. This therefore cleans up desk space and prevents them from seperating due to the cables moving them. 

There is a bumped forward part in the back to prevent the kvm from moving backwards while pressing the switch button. Still, using some double sided tape in addition may not be a bad idea if you still encounter problems with the kvm moving due to the cables. I havent needed this though.

I included the step file if you want to make a remix. 

Prints easily in just 2 hours, no support required :)
