Because I did not have long enough pins to attach a RPI ZeroW to the back of the motherboard I mixed two designs together to create an external mount.
This remix of two existing designs will allow you to connect the board using 6 regular breadboard wires or any other method that you prefer and still keep the PI attached to the back of the mainboard case.

Print instructions

Best results using PET(G) or any other material that resists better to temperature than PLA. RPI Zero W or the PSU can heat up and deform the model over time if printed with PLA.
Supports are needed.
