This is a little Bracket to fit in the original Case of sumpfing (https://www.thingiverse.com/thing:2503257). Her case is for the smaller version of the NodeMCU, I just clipped of the original mounts and glued my littel bracket in place. Used PLA Sticks to rivet the Board to the Bracket.
Print time: 6 min
Designing it: 20 min
Printing the original housing: 2h

So at the end, very good workaround! :-)
