Take a moment to review the components in the circuit diagram. This illustration is meant for referencing wired connections - The length of wire, position and size of components are not exact. 

The Slide switch will connect to the Feather board and will need to be 70mm for the GND and 50mm for the EN pin

CharliePlex Featherwing connects the Feather.
The connections for SDA and SCL wires will need to be 70mm long. 
3V and GND connections can both be 80mm long 

LIS3DH connects to the top of the Feather via the 3d printed mount and will need to be 40mm long for 3V, GND, SDA and SCL connections.
