Not all of my Raspberry Pi PoE Hats came with the metal standoffs, and the metal standoffs don't work in the Official Raspberry Pi Case, so I made some plastic ones. I used M2.5x5 screws to hold them to the board, and they press-fit into the official Raspberry Pi case.

Pretty simple, but works well.

I included the extremely simple Sketchup file, in case anyone needs it. It's just a cylinder 5mm OD, 2.5mm ID and 9mm high.

If your printer makes the ID hole too large or small for a 2.5mm screw, you might have to tweak your slicer or something.
