By default it has a 25 mm in diameter rod cutout with the length of 1090 mm for strength and stability.
There are also pins and mounts models onto the objects so you can easily put them together.
There is both clean and textured grip, in case you wish to resin print it or wrap it manually, and there is a part with and without the eagle at the end if you wish to use it without it.
The teeth/chain is split into 6 parts. It prints easily, without support, same as 99% of the model - it also prints without support-
And there is also a small scale one, fully combined - for small scale resin printing.
