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.

Resurrecting an Ocean Liner from 1932

by

An Accessible Art Deco Project From Norman Bel Geddes

In 1932, legendary theatrical designer and industrial design pioneer Norman Bel Geddes published Horizons, a manifesto that helped define the Streamline Moderne movement. Among his most radical concepts was an aerodynamic, teardrop-shaped ocean liner affectionately dubbed the “Whale.” Designed with a smooth, completely enclosed superstructure, internal lifeboats deployed via launch chutes, and a futuristic aircraft hangar built directly into its giant twin funnels, this 1,083-foot titan was envisioned to slice through the Atlantic and shave an entire day off transatlantic crossings.

while this image is ai, the model is made by us in endtas studio.

Because the real-world ship was never built, it exists today only in historical patent blueprints, speculative illustrations, and archive records. Now, a new 3D-printable model from endtas brings this unbuilt legend onto desktop printers and into the water.

Arcturus‑Class Submarine

by

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

by

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

by

A Classic Wooden Speedboat Reimagined for the Maker Community

Removable Canvas Top is also included

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

by

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.

The Lun-Class Ekranoplan RC-Ready

by

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

by

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:
