It's made for the LOLIN D1 Mini v4.0.0. The case doesn't fit older versions of the D1 Mini with micro-USB or components on the backside.

I designed this case specifically for my setup:
New version is a little bigger, so the fit isn't as tight.
If you print this model using a different material, on a different printer, or at a different layer height, the closing mechanism might not work as well.
The author marked this model as their own original creation.
