I made a little RPi Zero W case for my octopi setup since I couldn't find anything specific for it. It made to be mountable using a couple of M4 wood screws.

The whole design uses no extra hardware and everything should be able to press fit together (depending on your printers tolerances). You will want to insert the RPi camera header first to prevent the little black tab from breaking.....trust me, I learnt the hard way.

The STEP and F3D files are also available in case you want to remix it or customize the design in any way you please.
