I needed a housing for the ESP-Wroom32 development board.
Digging in the box of ancient electronics i found a 40 pin IDE-cable that i use as socket for the board which has 38 pins on it. If you want to replicate this, beware of newer cables that have 80 lines or keypins.
The .stl does not contain the bricks i added as holders to fit the slaughtered floppydrive; a freecadfile is added where you can customize your housing, several parameters are adjustable in a spreadsheet. Remember to add some space as your material may shrink.
Also notice that there is no roof, i will use foil to get a minimum damp to the radiosignals.
Assembly: first set up the waves between the two drive connectors. Then move the mainboardconnector through the sidehole inside out. the other connectors remain inside. I needed a hook to raise the connectors again...
This thing fits well for me as it is, although it surely could be improved quite a lot. Feel free to do so.

I found out that my project for a smart boat / caravan can be set up best and cheap with the bays of two old computercases. These are placed centrally and all the electronics i want to put in there can be set up as modules. The floppy now contains the CPU for the system and the radios (wlan, bluetooth). The front cover is under construction. Looks like a good plan NOW.
But even if you just want to insulate your ESP-board from short circuits while beholding it connectable this case might be good for you.
