This is the adapter for EVA 3 carriage. It would be used like the other adapter avaible for the carriage (like for orbiter 2.0 or LGX lite).
it needs 2 x m3 12mm to lock the extruder to bracket, additionally you can use another 2 x m3 12mm to lock it from behind .
BETA model, untested, but it should work. If someone will test it, i can eventually improve it.
