Panasonic Lumix BLG10E battery replacement for external power source

<p>My GX80 (and probably more Lumix cameras that use BLG10E battery) have one crappy lack/disadvantage. They cannot be powered from USB, but only charged... I'm designing a big battery grip, so I needed some input "dummy battery". Wouldn't destroy almost new battery just to get its case, so I designed a dummy battery that fits camera's battery connector but also fits "external power connector" placement in battery cover. Now I can connect few 18650s or even an external power supply.</p> <p>Original dummy battery and non-powered grip cost so much that buying Prusa Mini only for this project would be fully-paid tool.</p> <h3>Print instructions</h3><p>Print my 3mf file with 0,2mm layer, 100% fill with option "supports everywhere" on. I added "support block" modifiers to print supports only where they are really needed.</p> <p>Inside printed case, just place a PCB (1,5mm max thickness) emulating battery connectors plus some electronic. Glue in your favorite connector or cable in 4mm hole, it will fit your camera's external power hole.</p>
