Hey,
I've been lurking for a while now, and now it's time to post something. I have a GX80 for a few months now. Last week I found the following video about a DIY windbreaker for the built in MIC.
Now I thought that I could design something similar that could be 3D printed. So I did tonight. I still need to find some fabric to test it, but if it works I'll share the files.
