Just sharing with you a 3D printable design for the Victron Lynx Distributor M8 (not sure if it fits in the M10 version) which allows smaller gauge wire to be run out the back end without opening up the whole back end of the device.
Includes removable inserts to close out the slots in the back.
Of note, slots with removable inserts are used because once you get terminal rings crimped to the wires that go inside they will not longer just pull through the holes.
Includes (free and open source) PRUSA Slicer files, GCODE, and Fusion 360 Design source files.
