Here my remix from this Design: https://www.thingiverse.com/thing:4780515/remixes

###################################

I prepared the model for threaded inserts:

For Wemos and Mosfet:
M2,5 x 4,0

For Top:
M3 x 5,7

Add holes for Hollow connector 5,5/ 2,1mm

And enlarged the case for more space. Both in height and width.
