About this 3D model

My WD TV Live Hub is taking up desk space and is not in the intuitive place when pointing the remote so I am going to hang it from behind my monitor using 2 of these brackets. NOTE: Work in progress and I have yet to print (the pin causes a challenge unless supported.) Code is not very clean yet and is not really correctly parameterizable - BUT... It is close to what I want. Will print it in a bit. Added a pic of my first trials. UPDATE: Added roundedBox and new pic
