Arcturus‑Class Submarine

The Future of Stealth, Now at Your Desk

Where Science Fiction Meets the Workshop Bench

In August 2022, at the Army‑2022 defence expo, the Rubin Design Bureau unveiled a concept that looked more like a low‑observable aircraft than a traditional submarine. Named Arcturus (Арктур) after the brightest star in the northern celestial hemisphere, the design is the Russian answer to a new generation of ballistic‑missile submarines (SSBNs) that will eventually replace the Borei class. While the real vessel is still a paper project – its keel isn’t expected to be laid until the late 2030s, with operational capability projected for the 2040‑2050 timeframe – its faceted, angular hull and revolutionary propulsion system have already captured the imagination of naval analysts and hobbyists worldwide.

At EndtaS we decided to bring that future a little closer to the present. Our 75 cm Arcturus‑Class Submarine is a highly detailed, fully articulated 3‑D printable model that captures the spirit of Rubin’s concept while remaining practical for home printers. This article dives into what makes the real Arcturus special, what we’ve added to our 1 : ~200 scale replica, and how you can build it at home.

USCG Point Class Cutter

18 July 202604 July 2026 by Webmaster

A New RC-Ready Addition to the Endtas Collection (1:34 Scale)

We are pleased to announce the release of our latest large-scale printable vessel, the USCG Point Class Cutter, a detailed 1:34 scale model inspired by one of the most successful patrol boat classes ever operated by the United States Coast Guard.

Built between 1960 and 1967, the Point-class cutters were designed as versatile coastal patrol vessels capable of carrying out search and rescue, law enforcement, fisheries protection, anti-smuggling operations, and military duties. The class became particularly well known during the Vietnam War, where several Point-class boats were transferred to Southeast Asia and served in Operation Market Time, conducting coastal interdiction and patrol missions. Compact, fast, and highly maneuverable, these vessels earned a reputation for reliability that kept many of them in service for decades.

SolaRay Drive

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.

SMS Sachsen Ironclad

19 May 202606 May 2026 by Webmaster

A Coastal Defender from the Early German Empire

the scene is AI generated but the model is ours, made by human hand every curve and point.

The SMS Sachsen was the lead ship of the Sachsen-class ironclads, a group of four armored vessels built for the Imperial German Navy in the 1870s. Alongside her sister ships—Bayern, Württemberg, and Baden—she represented a distinctly different approach to naval warfare compared to the ocean-going ironclads of Britain and France. Rather than projecting power across distant seas, these ships were designed with a more focused mission: defending Germany’s coastline and controlling the confined waters of the North Sea and Baltic.

This role shaped every aspect of their design. The Sachsen-class ships were relatively compact but heavily armored, with a low freeboard and a strong emphasis on protection and firepower over range. Their layout reflected the transitional nature of naval engineering at the time—positioned between earlier broadside ironclads and the more advanced turret ships that would follow. Central battery arrangements, thick armor belts, and powerful main guns gave them serious defensive capability, even if their seaworthiness in rough open water was limited.

Although not as famous as later battleships, the Sachsen-class played an important role in the early development of the Imperial German Navy. They embodied a strategic mindset focused on coastal defense, deterrence, and controlled engagement, rather than global reach. Over time, as naval doctrine evolved and larger, more capable ships entered service, the Sachsen-class became less central—but they remain a fascinating example of a navy defining its identity during a period of rapid technological change.

Sectioned Ship-of-the-Line Model

04 December 2025 by Webmaster

130-Gun Warship Cross-Section

This detailed sectioned model is based on two of the 19th century’s greatest first-rate warships: the French Montebello and the Ottoman Mahmudiye. Using structural cues from both vessels, the design captures the architecture of a 130-gun, three-deck ship of the line while presenting its interior through an elegant open cross-section.

The Caspian Monster

22 March 202625 October 2025 by Webmaster

When the Soviets Made a Plane That was also a Ship

In the heat of the Cold War, when the world’s superpowers were racing to outfly, outswim, and outthink each other, the Soviet Union quietly unleashed something that defied all categories. It wasn’t quite a plane, not really a boat, and certainly not a submarine — yet it managed to borrow a bit from each. They called it the KM Ekranoplan, but NATO, baffled by satellite photos of a gigantic winged machine skimming the surface of the Caspian Sea, simply dubbed it “The Caspian Monster.” The name stuck, and deservedly so.

The Ship That Couldn’t Stay Afloat: The Breathtaking (and Brief) Voyage of the Vasa

In the golden age of naval might, when ships were the superweapons of empire and pride floated on salted winds, Sweden set its sights on maritime glory. Enter the Vasa, a warship so lavish, so majestic, and so doomed that it sailed straight from royal ambition into the sea floor—in under 20 minutes.

This isn’t your average tale of maritime disaster. The Vasa’s story is equal parts engineering marvel, political drama, and tragicomic miscalculation. Continue reading for the rest of the story and a free STL file for 3d printing your own Vasa. We also have a paid model, 1m long, RC compatible, and with more details.

Ton-Class Minesweepers

30 April 202619 May 2025 by Webmaster

The Silent Workhorses of the Cold War now is here as an RC-Ready 3d model.

During the tense decades of the Cold War, the Royal Navy quietly operated a fleet of specialized vessels designed not for battle, but for survival—of fleets, ports, and shipping lanes. These were the Ton-class minesweepers, an unglamorous yet vital class of ships that ensured safe passage through mine-infested waters across the globe. Though small in size, their contribution to post-war naval security and NATO maritime operations was significant.

(wood paneling seen in the renderings are textures only, the 3D model has flat deck surfaces.)

This article includes a 1m 3D model of the Ton Class that can be printed, painted and used for display purposes. The interior of the model is empty and hull has approximately 5-6mm thickness all around making this model a candidate to be converted to a remote controlled boat. There is also a free STL file for a tabletop display model of the Hull Class. You can download it by using the link at the end of the article. Enjoy and please share this page on your social media. If you want to purchase the paid model, HERE IS THE PURCHASE LINK.

With the latest update, the Ton-class model has evolved from a detailed display project into a fully functional RC-ready platform. The internal structure has been carefully reworked to support real-world components, including propulsion systems, steering mechanisms, and onboard electronics, while preserving the clean external lines of the vessel. This transformation significantly expands the scope of the model: what was once primarily a visual recreation can now become a working representation of a classic minesweeper. By combining historical fidelity with practical engineering, the model offers builders the opportunity to experience the Ton-class not just as a static object, but as a dynamic and interactive project on the water.
