Build the Unsinkable Legend

Some boats are remembered for their speed. Others are remembered for their beauty. The CG-36500 Motor Lifeboat earned its place in history through courage, reliability, and extraordinary engineering. Designed by the United States Coast Guard to operate in conditions that would force most vessels back to harbor, the 36-foot motor lifeboat became one of the most successful rescue craft ever built. Its defining moment came on 18 February 1952, when CG-36500, commanded by Boatswain’s Mate First Class Bernard Webber, crossed the treacherous Chatham Bar during a violent winter storm to rescue 32 sailors from the tanker SS Pendleton. The mission has since become one of the most celebrated rescue operations in Coast Guard history and inspired the film The Finest Hours.

At Endtas, we wanted to recreate not only the appearance of this historic vessel but also its practical, purposeful character. The result is a highly detailed 1:16 scale model measuring approximately 70 cm (27.6 inches) in length. Every major fitting, deck accessory, and structural feature has been recreated from historical references to produce a model that looks equally at home on a display stand or out on the water. With more than 100 high-detail components, the model offers an engaging building experience while remaining practical to print on everyday desktop FDM printers. Our philosophy has always been to combine historical accuracy with thoughtful engineering, ensuring that every project is enjoyable to build as well as visually authentic.

A Classic Wooden Speedboat Reimagined for the Maker Community

There are few boats that capture the elegance of the early twentieth century quite like the classic gentleman’s runabout. Characterized by their polished mahogany hulls, long foredecks, graceful tumblehome sterns, and powerful inboard engines, these boats became symbols of craftsmanship and leisure during the golden age of recreational boating. Inspired by this timeless style, our latest project brings the spirit of these handcrafted classics into the world of additive manufacturing. The Gentleman’s Runabout combines authentic proportions with modern engineering, resulting in a large-scale 3D printable model that is equally suited for display and radio-controlled operation. The model is available through our Cults3D store alongside our growing collection of RC-ready maritime designs.

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.

From Sea to Shore: Exploring Mechanical Kinematics

At EnDTaS, our passion has always been the intersection of complex design and additive manufacturing. While our primary focus lies in the depths of the ocean and the stealth of naval architecture, the core of our philosophy is the same: Functional Engineering.

Engineering isn’t just about massive hulls or tactical propulsion systems; it is about the elegant movement of parts. It is about how a simple linkage can translate a human gesture into mechanical work. To explore this concept in a more accessible, tactile way, we are excited to introduce our 3D Printable Toy Front Loader.

The Lun-Class Ekranoplan RC-Ready

21 June 2026 by Webmaster

Evolution of the Giant.

For those who have followed our journey at EnDTaS, the Lun-Class Ekranoplan has always been more than just a model to us—it is a symbol of audacious, boundary-pushing engineering. In our previous release (click here to open it in a new tab), we focused on capturing the sheer scale and imposing presence of the Soviet “Sea Monster,” providing a high-fidelity 1-meter replica for collectors and historians.

But for us, a static model is only the beginning. As a studio dedicated to Experimental Naval Designs, we asked ourselves: How do we move this behemoth from the shelf to the water?

From Display Piece to Dynamic Platform

The challenge of the Lun-class is its inherent contradiction: it is a massive, heavy-looking vessel that must remain light enough to exploit the ground effect. To translate this into a successful RC project, we couldn’t simply use the same geometry as the display model. Weight is the enemy of performance.

We are proud to introduce the Lun-Class Ekranoplan RC-Ready Lightweight Edition. This isn’t just a refinement; it is a complete engineering overhaul designed specifically for the motivated maker and RC enthusiast.

USS Keokuk

21 May 202619 May 2026 by Webmaster

A Modular 1:48‑Scale Ironclad

When the Civil War broke out, the U.S. Navy was forced to rethink warship design. Traditional wooden hulls could not survive the new, high‑powered guns that were being fielded on land. In response, designers began experimenting with iron‑clad hulls that would shrug off cannon fire and resist the very bullets that had once devastated wooden ships. The USS Keokuk, launched in December 1862, was one of the first of these experimental “casemate” ironclads.

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

With a 159‑foot length, 36‑foot beam, and a displacement of 677 long tons, the Keokuk was built from a solid iron hull, with a wooden deck and a thin layer of filler armor that protected the gun positions. Powered by two 250‑hp steam engines that drove twin 7‑foot screws, the vessel could reach 9 knots – a respectable speed for a warship of its time.

Armed with two 11‑inch Dahlgren smoothbore guns and a ram bow, it joined the South Atlantic Blockading Squadron in March 1863 and saw action in the Charleston campaign. Though its operational record was brief, the Keokuk’s design paved the way for the next generation of iron‑clad warships.

Our 1:48‑scale file pack brings the historic ironclad into the hands of hobbyists and RC enthusiasts alike. The design has been carefully optimised for 3‑D printing while preserving the ship’s iconic profile:

SMS Sachsen Ironclad

19 May 202606 May 2026 by Webmaster

A Coastal Defender from the Early German Empire

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.

The Hamilton-Class High Endurance Cutter

05 May 202601 May 2026 by Webmaster

The Coast Guard’s Workhorse for Half a Century:

A New Kind of Cutter for a New Era

When the United States Coast Guard began planning its next generation of large ocean-going cutters in the early 1960s, the service had been operating converted World War II-era Navy vessels for nearly two decades. The ships were aging, increasingly difficult to maintain, and unable to fully meet the demanding operational requirements of a modern Coast Guard. What emerged from that planning process was one of the most successful and enduring cutter designs in the history of American maritime law enforcement — the Hamilton-class High Endurance Cutter, a vessel so capable and well-conceived that it would serve the Coast Guard for nearly half a century.

The initial contract for the lead ship, USCGC Hamilton (WHEC-715), was awarded to Avondale Shipyards in New Orleans, Louisiana in January 1964, with construction beginning shortly thereafter. Hamilton was launched on December 18, 1965 and commissioned on March 18, 1967, named for Founding Father Alexander Hamilton, the first United States Secretary of the Treasury and founder of the United States Revenue Cutter Service. She was the first genuinely new high-endurance cutter the Coast Guard had received in more than twenty years, and from the moment she entered service it was clear she represented a significant leap forward in capability. Originally envisioned as a large-scale procurement, long-range plans called for up to 38 cutters to be constructed over the following decade, but budget constraints and the wind-down of the international ocean stations program reduced the authorized number to just 12 ships, all built at Avondale between 1965 and 1972.

Freedom-Class Littoral Combat Ship

01 May 202620 March 2026 by Webmaster

A New Kind of Warship

When the United States Navy introduced the Littoral Combat Ship concept in the early 2000s, it represented a fundamental rethinking of what a modern surface combatant could and should be. Traditional warships were large, heavily armed, and designed for blue-water operations far out at sea. The LCS was conceived for an entirely different environment — the littoral zone, the shallow coastal and near-shore waters where conventional warships struggle to operate effectively, yet where a growing number of real-world threats were emerging. Fast, nimble, and built around a modular mission system architecture, the LCS was envisioned as a vessel that could be rapidly reconfigured for entirely different combat roles depending on the threat — surface warfare one week, mine countermeasures the next, anti-submarine operations the week after.

The Freedom Class is one of two LCS variants developed for the US Navy, built by Lockheed Martin and Fincantieri Marinette Marine at their Wisconsin shipyard. Where its sister variant, the Independence Class, adopted a radical trimaran hull form, the Freedom Class took a more conventional semi-planing monohull approach — sleek, fast, and remarkably capable for its size. Displacing around 3,900 tons at full load and stretching just under 116 meters in length, Freedom-Class ships are powered by a combined diesel and gas turbine propulsion system driving quadruple waterjets, allowing them to reach speeds well in excess of 40 knots — making them among the fastest warships of their displacement in any navy in the world.
