I started thinking about different forms and finally found this stuck in the ring when I was playing around with the XLR interface. You need to use NEUTRIK or Jiasound XLR connectors in the design. Maybe others can also work, you can tell me in the comments.
This is a hood for GH5 and S1H. In this design, a rubber strips is needed. For GH5, a 1mm thick and 10mm wide strip is needed. S1H needs a 2mm thick and 10mm wide strip.
This is the support of the Logitech C270 for the Xiaomi Mi ScreenBar. The design needs to use M3 screws and M3 injection nuts, if you find it troublesome, you can also use cable ties.
