The USCGC Cape Class

The Sub-Chaser That Saved the Long Weekend

From Cold War Depth Charges to Perfect Lake Sovereignty

There is a specific kind of magic that happens when you take a vessel designed to hunt Soviet submarines in the Atlantic and scale it down to rule your local pond.

During the tense dawn of the Cold War, the United States Coast Guard realized it needed a very specific tool: a fast, rugged, shallow-draft cutter that could sprint into the waves, drop a pattern of anti-submarine ordnance, and survive brutal coastal weather. The answer was the 95-foot Cape-Class Patrol Boat.

With their distinct, angular aluminum superstructures sitting on unforgiving steel hulls, these cutters spent decades conducting critical search-and-rescue operations, drug interdiction, and maritime safety patrols. They were loud, they were tough, and they were utterly reliable.

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.

CG-36500 Motor Lifeboat

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.

Gentleman’s Runabout

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

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.

3D Printable Front Loader

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.

SMS Sachsen Ironclad

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.

Freedom-Class Littoral Combat Ship

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.

Thornycroft Coastal Motor Boat 55ft

Britain’s Secret Weapon of the Seas

From World War I Torpedo Raider to Modern 3D-Printed RC Model


Origins: A Bold Idea from Junior Officers

Few naval weapons have such an unlikely origin story as the Coastal Motor Boat (CMB). In the summer of 1915, three junior officers of the Harwich Striking Force — Lieutenants Hampden, Bremner, and Anson — hatched an audacious proposal: could a small, fast motor boat, armed with a torpedo, travel over enemy minefields and attack Imperial German Navy ships at anchor in their heavily defended bases?

The Admiralty gave tentative approval, and a Staff Requirement was issued for a new type of vessel to serve in the North Sea. The specifications were demanding. The boat had to be capable of at least 30 knots when fully loaded, carry enough fuel for a meaningful radius of action, and be armed with torpedoes, depth charges, or mines, supplemented by light machine guns. Several established shipbuilders were approached, but only one company believed the requirement could actually be met: John I. Thornycroft & Company.

Tupolev G-5 Torpedo Boat

History, Design, and Our 1:24 Scale 3D Printable Model

The Tupolev G-5 occupies a unique place in naval history as one of the most distinctive fast attack craft of the interwar and early Second World War period. Designed in the early 1930s by the Tupolev Design Bureau, the G-5 was the Soviet Union’s answer to the growing demand for high-speed torpedo boats capable of striking larger surface vessels and withdrawing before retaliation. Built primarily from duralumin, the same lightweight alloy used in aircraft construction, the G-5 reflected its aviation heritage in both material choice and overall design philosophy.

Compact, aggressively streamlined, and extraordinarily fast for its time, the G-5 was capable of speeds exceeding 50 knots under ideal conditions, making it one of the fastest military vessels of its era. It carried its torpedoes externally, launched rearward from open cradles—a bold and unconventional solution that allowed the hull to remain slim and hydrodynamically efficient. Over its service life, the G-5 appeared in numerous configurations, with variations in armament, deck equipment, crew layout, and superstructure, adapting to changing combat requirements throughout the 1930s and into World War II.
