Designed as vertical stand for holding a MacBook Pro. Pictured is my 17" 2011 unibody MBP. Plenty of clearance for ventilation and the 2011 MagSafe cable. The slot is 26mm wide.

I am the original designer of the Elegant Arch.  I've moved the design over here.  On Thingiverse are a number of remixes for newer laptops.  However it's easy enough to just scale the model to fit any laptop.
