I wasn't going to upload this but figured it may help someone out.  I looked all over for a case for the Waveshare POE IO board for the CM3 and CM4 Raspberry Pi.  The most I could find was a case top.  I was going to purchase their metal case but tariffs had the shipping at $500.  

Anyway, looking at Waveshare's site, they had a case model that was downloadable.  Just a box really with indentations for cutouts.  Pulled that into Tinkercade, hollowed out, cut out the indentations and printed.  Worked out fine, if not a bit of a tight fit.
