• Modelling was done from a sparse set of measurements.
• After modelling was done arbitrary measurements of any feature could be done.
• Easier than measuring every possible dimension when needed.

Planning

• Longer M.2 2280 slot is used for high capacity SSD.
• Shorter M.2 2242 slot is available but in a less convenient location.
• Left speaker can be removed to make room for Oculink port.
• M.2 2242 slot has 1mm of clearance for bottom side passive components.
• Option 1: Very narrow 12mm gap between M.2 2280 connector and internal display connector for single board design for side Oculink port.
• Option 2: Vertical space underneath M.2 2280 slot for routing with a flex pcb design that has a side Oculink port.
• Option 3: Use vertical Oculink adapter and have port on bottom instead of side of laptop.
