Preparing Model for 3D Printing - cut meshes where Texture is transparent?

Hey Guys, currently I’m preparing a model for 3D Printing.
The Model I want to 3D print has some Textures with transparencies but the meshes, ofc, are still there (so the 3D Printer won’t recognize that the model has holes on this places.

Is there a way to tell Blender to cut away the faces/faceparts where the texture is transparent or the texture has a specific color?
