Fully Redesigned Azimuth Propulsion System
One of the major highlights of this project is the newly redesigned azimuth propulsion pod system. Unlike static decorative propellers, these pods were engineered with functional movement and RC experimentation in mind.
The package includes:
- Functional azimuth pod housings
- Steering pulley systems
- Bevel gears
- Spur gears
- Propeller shafts
- Servo brackets
- DC motor brackets
- Shaft supports and bearings
- Modular mounting components
The internal hull geometry was also redesigned to simplify:
- Wiring
- Mechanical linkage routing
- Motor placement
- Servo access
- Structural reinforcement
This makes the model highly attractive for advanced RC builders looking to develop custom propulsion systems and directional thrust control. (Cults 3D)

Optimized for Large-Scale FDM Printing
The hull is separated into multiple upper and lower sections to fit standard consumer 3D printers while maintaining structural rigidity and clean alignment.
The modular segmentation allows:
- Easier print orientation
- Reduced support usage
- Better surface quality
- Easier transportation
- Simplified maintenance or upgrades
The hollow hull construction also leaves substantial interior volume for:
- RC electronics
- Battery systems
- Wiring
- Ballast
- Lighting systems
- Custom reinforcement structures
Display Model or RC Conversion Platform
While the model already works exceptionally well as a large-format static display build, its internal engineering also makes it suitable for ambitious RC conversion projects.
Potential upgrade possibilities include:
- Functional azimuth steering
- Twin or triple motor propulsion
- LED navigation lighting
- Rotating radar systems
- Sound systems
- Remote-controlled deck functions
Because the azimuth system remains experimental, some sanding, drilling, fitting, or reinforcement may be required during advanced RC implementation. Builders comfortable with custom fabrication and mechanical tuning will find considerable engineering flexibility in the design.
Early Builder Advantage
As a newly released project, this model continues to evolve through real-world builder feedback. Early adopters benefit from:
- Ongoing refinement
- Community-driven improvements
- Potential future updates
- Experimental engineering opportunities
The design was developed over weeks of modeling and refinement to balance:
- Printability
- realism
- modularity
- structural integrity
- and RC adaptability.
What Is Included
The downloadable package includes:
- 115+ STL files
- Full-color assembly 3MF
- Modular hull sections
- Functional azimuth pod parts
- Structural connectors
- Deck accessories
- Detailed superstructure components
- Display stand
- RC-oriented internal layouts
The complete package is intended to provide a satisfying long-term build experience resulting in a visually striking modern tugboat model suitable for display, engineering experimentation, or RC development.
