This is my Pi Zero Case designed mainly to hold my Pi Zero W , but also works with the normal Pi Zero as well with wifi dongles.
Its designed to allow the Pi to just slide in and the power cord keeps it in place. As it uses a sleeve to hold the Pi it also means it is quite robust and doesnt break mounting lugs and also does not neeed screws or bolts to hold it in.
In addition, the top can take a Neopixel LED ring for added shazam and a rotary encoder as well if you want to have some input.
I've managed as well to fit an I2C audio amp and rectangular speaker inside as well. It all prints easily and the only trick is that i have printed the LED diffuser in PETG with 0% infill.
If you just want it as a case, then you can omit the light ring and I will be adding a knob replacement that is a snug fit so that it all fits nicely.
Hope you like it and it makes a change from the standard flat rectangles.

I also have an instructable to use this case and a Pi Zero to control mains sockets via Alexa and emulating RF signal required for the plugs.
For those that have asked I have some of these available in etsy
It has all been printed in PLA+ at .21875 and 20% infill. The LED diffuser was printed in PETG with 0% infill
The sleeve was a remixed/remixed version - of this original sleeve - https://www.thingiverse.com/thing:1161310
