5 pieces can be seperated, though the outer baige pieces cannot be seperated immediently, you would first have to take out the two pins which are interlocking them between the blue interconnector and the outer beige peices,
i thought of this via mechanics, and while playing around with other scene parts, however i did make these peices myself, i just used the peices for a refrence then. this basically shows how interlocking works.
