Summary These rails vertically mount a macbook pro on a wall or under a desk. It compatible with MBPs from 2013 to now. Newer model laptops will benefit from shrinking the depth by 2-3mm in your slicer. Compatible with portrait and landscape mounting. The bracket dimensions are: h: 155.6mm w: 51.4mm d: 32mm There are vent holes along the back to allow the side intakes to breathe and 1cm standoffs to give the bottom of the computer room to radiate heat. I've been using my mac in this configuration for years with no heat problems. This bracket allows me to mount the laptop this way without worrying about tipping or getting bumped off my desk.

Best print orientation is so the filament lines run parallel to the slot.
