A Modular Approach to Tactical Aquatic Propulsion
In the world of maritime engineering, propulsion is everything. Whether you are designing a stealth vessel, a deep-sea explorer, or a rapid-response rescue craft, the ability to move efficiently through the water is the primary challenge.
At EnDTaS, we believe that high-end engineering shouldn’t be locked behind corporate walls. To push the boundaries of the maker community, we are introducing the SolaRay Drive Unit—a versatile, 3D-printable propulsion system designed for the next generation of aquatic projects.

The SolaRay Concept: One Core, Infinite Applications
The SolaRay is not a single-purpose tool; it is a modular drive platform. We have engineered it to be the “beating heart” of various aquatic systems. By separating the propulsion unit from the main hull, we allow builders to customize their craft based on the specific mission requirements.
We have identified three primary applications for the SolaRay system:
1. Solar-Assisted Water Scooters (DPVs) For divers and explorers, the SolaRay provides the basis for a Diver Propulsion Vehicle. When paired with solar-charging arrays, the unit transforms into a sustainable transport system, extending the range of the user and reducing the reliance on heavy, limited battery packs.
2. Remote Operated Vehicles (ROVs) The SolaRay’s compact and efficient geometry makes it an ideal candidate for ROVs. Its design allows for precise maneuvering and stability, providing a reliable thrust system for underwater exploration, inspection, and mapping.
3. Rescue and Support Platforms In emergency scenarios, speed and reliability are non-negotiable. The SolaRay can be scaled and integrated into lightweight rescue platforms, providing a rapid-deployment propulsion system capable of transporting critical supplies or assisting swimmers in distress.
Engineering for the Additive Age
The SolaRay Drive Unit was designed specifically for the strengths of 3D printing. We didn’t just design a part; we designed a system that considers the realities of the workbench:
- Optimized Fluid Dynamics: The housing and impeller geometry are designed to maximize thrust while minimizing drag, ensuring that every watt of power is converted into forward motion.
- Modular Integration: The unit features standardized mounting points, making it easy to integrate into existing hulls or entirely new experimental designs.
- Sustainability Focused: By optimizing the drive for solar-assistance, we are exploring the viability of “green” tactical systems—reducing the carbon footprint of aquatic exploration.
Open-Source Innovation & #BEACHXCULTS
In the spirit of collaborative engineering, we have made the SolaRay Drive Unit completely free for non-commercial use. We believe that by providing the community with a professional-grade propulsion base, we can spark a wave of new, experimental aquatic designs.
We need your support! The SolaRay is our official entry for the #BEACHXCULTS contest on Cults3D. To help us bring more tactical aquatic systems to the maker community, we would be incredibly grateful if you could visit our product page, give it a Like, and Share it with your fellow builders. Your engagement helps us climb the rankings and continues to fuel our design process.
