I tried a bunch of 38pin cases and none seemed to fit the board I bought from Amazon, so I made this one.

This case was designed to fit this small footprint ESP32-WROOM-32D from Amazon because I couldn't find a case that fit it. https://www.amazon.ca/dp/B0C9VSYS4N?th=1
I made this in FreeCAD from scratch, but the design is based on the appearance of two different models I found on Printables, and also some of the comments about those designs.

For my case, I wanted the ESP pins to be accessible externally, but wanted the case to sit flat if nothing was plugged into it. So the pin cut outs in the bottom of the case will take standard dupont connectors but the pins are recessed so they don't stick out.
I lost at least 3 of the small buttons for the Mihai case, so I looked around and found the flapper style buttons on the Rasmussen case and went with those.
Also, being an old fart, I forget quickly, so I added Icons beside the buttons on the top of the case. The flash icon turned out okay, but the reset button is rather lame.
I also added a slot for a screwdriver in the seam so the case can be easily pried open.
The board is loose enough it can be removed easily, but is held in place by some retaining posts in the top so it doesn't move around.
Printed using default settings (0.4mm nozzle, 0.2 layer, bed 60C, Nozzle 220C, 300mm/s, 15% infill) on my Qidi Xsmart 3
Probably didn't need the LED hole in the top (at least for White PLA) but it might be helpful if printed in a more opaque filament…
I tried printing text labels (Flash and Reset) but the text was so small it wasn't legible, hence the icons instead.
I included the Freecad file, in case someone wants to alter this for their own use.
