Dummy Battery / DC Coupler for DMC-GH3 GH3K DMC-GH4 GH4K DMC-GH5 DMC-GH5S. Similar to DMW-DCC12. It can be assembled with a few M2 X 6 screws. I have made provisions for 5 screws. I have printed them without supports and didn't face any problem. For the battery pins, I just glued dupont style pins (might need to clean them after gluing to make sure they are conductive). DC pigtail power cable pairs can be used to build the complete system using a buck converter and a 12V/24V power supply. I have a GH5S. The official power supply DMW-AC8 specs says 8.4V / 2A. I tried using a buck converter "XL4015 5A DC-DC Step Down Adjustable Power Supply Buck Module" with a 12V 5A power supply. I adjusted the voltage on XL2015 to 8.4V and the camera works. I have also included the files for the XL4015 module case. (The XL4015 case dimensions might not be exact for your module). This is a work in progress as i would like to test the buck converter for safety properly.
