When I Klipperized my e3v3se, I didn't want the pi to hang on the outside, so I bought the external antenna (OPiZ3 uses IPEX-4 connector) and modeled this simple bracket to mount both the OPiZ3 and the LM2596S buck converter inside of the printer's body. It's held by 2 of the ex-screen screws.
The OPiZ3 and the LM2596S are held by a total of 6 M3x8 hex bolts.
Printed mine in ABS without supports, it is rigid enough to hold them both with no issues. I bet PETG with enough infill would also be just fine. I'm not sure about PLA because of the temperatures inside though, so I wouldn't recommend it, but you're always welcome to try it for yourself.
P.S.1 The LM2596S feeding from the stock PSU works fine for me so far, the OPiZ3 power consumption is quite modest.
In case you are willing to make the same mod - DO NOT FORGET TO ADJUST THE LM2596 OUTPUT TO 5V BEFORE(!) YOU CONNECT IT TO YOUR PI!
P.S.2 This project is still a WIP. I'm waiting for a 90-degree type-c adapter to connect the Pi to the MCU (for some reason, I don't want to use UART connection). When I receive it - I will model an outer cover for the wiring also.
