Blue Protector for 4-Port Stackable USB Hub HAT Compatible with Raspberry Pi Zero W

I purchased this specifically because I needed some kind of protector/enclosure for use with my Pi Zero W and a HAT. No other cases I could find fit this decidedly non-standard HAT (https://www.amazon.com/gp/product/B07T31S7TB/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&psc=1) but that's ok; this one was exactly what I wanted. I also appreciate that this case is open-air to promote cooling. The standoff screws were just barely too short to fit above the RJ-45 port on the HAT but there was enough room on them to unscrew the nuts slightly and make the whole thing fit securely.

Use the long screws on the base and use the nuts as a spacer. After that....easy easy lemon squeeze. Fit and finish excellent. Will buy again.

The acrylic top and bottom plates are of good quality, with a useful pinout diagram. My complaint is in regard to the cheap plastic/nylon screws/nuts/spacers. They do not thread very well, and are not easy to work with without damaging. It would have also been nice to include a diagram for assembly, as there were two size spacers and a number of nuts. I resorted to trial and error, which compounds the durability issues with the plastic/nylon screws. I used a combination of the included hardware with some metal spacers and screws I had. Not ideal, but got it mostly worked out. Used it with the USB/Ethernet HAT. The seller should really consider including metal hardware and at least a simple diagram showing suggested installation options.

It would have been helpful if the seller would've included an assembly diagram. You'll need a small Phillips head screwdriver to put it together.

This fits on my Raspberry Pi Zero 2 W that has a ethernet top hat I bought.

Fits nicely, used on top of an Ethernet/USB hat.

I had a cheap, $2 case from somewhere the eventually broke (the heat from the pi made the plastic brittle). So far, this case seems a lot nicer. Love the blue color.

The dividers provided had to be supplemented with other shorter ones between the USB HUB and the Pi for the underside contacts to connect properly. The wing edges around the GPIO pins promptly cracked and fell off. I managed to get it to all fit together so the bare bottom of the HUB was no longer exposed to the table, which was my primary concern.
