I didnt have a Pi Zero W, just a pi zero but had one of the Waveshare USB and 10/100 ethernet Hats that works with the pi zero, i extended the original model and then also added a few cut outs for access to one additional USB A port and the network port but blocks the mini hdmi port.

Iv added pictures but i had to print this in resin instead of FDM because my printer died. if you do use an FDM you will need to support the side that has the large cut out as it will droop a bit.
