The Bowden Chain comes with multiple benefits:
It keeps your four PTFE tubes neatly organized and makes your setup look awesome!
Each Bowden Chain-unit snaps easily together, so just print as many as you need — and don’t worry, each piece only uses 0.98 g of filament.

Assembly guide:

It’s also recommended that you assemble all your Bowden chains first, and then attach one PTFE tube across all the chain pieces. Once that first tube is in place, the whole setup becomes much more stable, and you can easily snap the remaining three tubes into place.
Easy peasy :)
