Book of Boba Fett Gauntlet Connectors
This is a custom-made BoBF gauntlet hose sleeve to simulate the real ones used, which were Airbrush air hose connectors and covered with heat shrink wrap.
I've included a remixed version of the "connectors" to accommodate a 6mm OD aluminum pipe.
The connectors and the wrap I would recommend using a Resin printer, but the wrap is better in PLA+ or ABS filament at 0.2 layer height.
