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 have provided two versions: Stand only, as well as a version including breakaway supports. PLEASE NOTE Some people have been having issues with the supports version, so it might be better to let you own slicer create supports for you!
This was printed on my Replicator2X and was designed to use the entire width of the build plate. I used a 35% infill and three perimeter walls. I suggest similar or even heftier settings. It is holding several thousand dollars worth of laptop...
