Seen here printed in PETG for slight flexiblity (keep reading). 

This mount is slightly oversized in comparison to the shape of the Mac mini. I see this as a design feature as it allows the mac to be tightly held in place with friction via pulling the mount's “arms” together when it's being screwed into the desk. In doing this, the mac is secured firmly in the mount and cannot be removed, nor does it any play or ability to wiggle when plugging in usb-c devices. I'm very happy with how this turned out!
