Here is a model of parts for the Clone Pilot armor from Phase 2. Only chest box and tubes, helmet not included. The tubes fit with a helmet, the link to which will be below. I showed the division into parts with different colors. There are small recesses in the box for attaching tubes. You can also install any other tubes.
