Case for Raspberry Pi Zero with the Hubpixed add-on hub. You'll probably want to add some rubber feet to the bottom to allow a ventilation gap and prevent sliding.
I'm pretty sure this will work for the HubPiWi as the layout appears to exactly the same minus one of the usb ports. I don't have one to test with, so please confirm in comments the fit of the case with the HubPiWi.
Note that the covering of the non-power usb port on the Pi Zero is intentional. You cannot use that port while the hub is attached.
Optimized for .4mm nozzle and .2mm print height.
