Slot in replacement for the back connector on the bottom frame. Same screw length.
To reduce total overhang, it sets on top of the bottom frame as much as possible.
Designed for what seems like a fairly standard receptacle like this https://www.amazon.com/dp/B07RQV2NPN
I also included the previous version I made that mounts on the side of the body in case you prefer that mount point. The side mount doesn't replace the connector, so you'll just need to use slightly longer screws.
I included the f3d file, but it's a bit of a mess.
Hardware:
Socket: https://www.amazon.com/dp/B07RQV2NPN
4x M3 heat set inserts (two for the side cover, two for the socket)
4x M3x5 socket head cap screws.
The author remixed this model.
