This is a large simple Bolt, the thread and bolt head (nut) are separated by a left hand thread.
The thread is hollow allowing for it to be used as a compartment.
The term lefty loosey, righty tighty doesn't apply here with the left hand thread.
There is a 1mm clearance.
Print dimensions are;
The thread is z=190mm x=94.62 and y=94.62
The bolt head (nut) is z=60 x=200 and y=173.39
You can shrink the dimensions down to 80% if needed.
