Despite being a replacement for many types of SSBNs, Borei-class submarines are much smaller than those of the Typhoon class in both volume[8] and crew (24,000 tons opposed to 48,000 tons and 107 personnel as opposed to 160 for the Typhoons). In terms of class, they are more accurately a follow-on for the Delta IV-class SSBNs.
I’ve made this model both for display purposes and for R/C enhusiasts. There are two separate file packs for each purpose. Display model is approximately 21cms long to fit most 3d printers. Surely it can be enlarged as you wish if you have a large enought printer. The RC model consists of a shell and dive-rudder planes. It is approximately 1 meters long and has 1mm thickness.

The Leyland-MCW B36D was an underfloor-engined single-deck bus manufactured for at least eighteen countries from 1949 to 1971. 3,564 samples were built at four factories (three in the UK, one in South Africa) from 1949 to 1971, with 1,299 Olympics (36%) built as right hand drive and 2,265 (64%) as left hand drive. It was a very durable heavy-duty bus which ran in arduous conditions for longer periods than ever envisaged by its designers.
300 of these B36D vehicles sold to the Istanbul municipal bus fleet in 1968/9 were named Leyland-MCW Levend, a word meaning a crack soldier. They served nearly to the year 2000. None were preserved 🙁
Here is Levend.
I’ve made a printable 3d model of the legendary bus which I’ve spent most part of my childhood and youth in it, travelling from place to place in Istanbul.
The bus model is animated, it has opening doors, running wheels, wipers, steering, suspension etc.

Here is a new robot vacuum for you. It is a mini with 150mm diameter so 3d printer friendly. Can be produced with most printers in one piece. Easy to assemble and produce by using reasonably priced standard parts. Get it and enjoy.
it has space for two motors, vacuum fan, 2 switches and upto 2 18650 batteries.
A single 50mm fan is used for generating the suction. Continue reading for more info, renders and STL files.
USS Nautilus (SSN-571) was the world’s first operational nuclear-powered submarine and the first submarine to complete a submerged transit of the North Pole on 3 August 1958.
Because her nuclear propulsion allowed her to remain submerged far longer than diesel-electric submarines, she broke many records in her first years of operation and traveled to locations previously beyond the limits of submarines. In operation, she revealed a number of limitations in her design and construction. This information was used to improve subsequent submarines.
Deep Submergence Vessel NR-1 was a unique United States Navy (USN) nuclear-powered ocean engineering and research submarine, built by the Electric Boat Division of General Dynamics at Groton, Connecticut. NR-1 was launched on 25 January 1969, completed initial sea trials 19 August 1969, and was home-ported at Naval Submarine Base New London. NR-1 was the smallest nuclear submarine ever put into operation. The vessel was casually known as “Nerwin” and was never officially named or commissioned. The U.S. Navy is allocated a specific number of warships by the U.S. Congress, but AdmiralHyman Rickover avoided using one of those allocations for the construction of NR-1 in order to circumvent the oversight that a warship receives from various bureaus.

Submarine 3d Model
Rotate the model
This is a 3d printable model of the well known NR-1. The details are as faithful to the real thing as much as 3d printing requirements allow. The model details are improved for enabling an easier printing with minimal supports. There is also a 1meter hull available for R/C model builders.

The Paltus-class submarine is a Russian special purpose mini-submarine of project 1851.1. Two boats were completed – AS-21 and AS-35 as a follow up of the single “X-Ray”-class boat AS-23 (Project 1851).
X-ray with various gripper options
The surface displacement is approximately 300 tons with a length of 98 feet (30 m). The propulsion comes from nuclear power with the operating depth in excess of 3,800 feet (1,200 m). The designer, according to Polmar was Sergei Bavilin who had designed the earlier diesel electric Project 865/Piranya small submarine of similar dimensions

I made this model a while back. It was lying around in my hard drives, so i’ve given it a quick update and tidying to be a 3d printable project. Here it is, continue reading for more images and STL files.
German engineers were able to create a number of interesting mini-submarine projects. One of them was a kind of crossing a submarine with a tank. This very interesting example was the ultra-small amphibious submarine “Seeteufel” (translated from German as “monkfish”) with a caterpillar mover. This boat was intended both for independent carrying out torpedo attacks and for delivering small groups of swimmers-saboteurs to the target of the attack.
.
Seeteufel was a rather unusual, even amazing, development. This “pocket” submarine was supposed to feel at home on the water surface, under water, and on land. This combat apparatus, as if descended from the pages of books by the famous science fiction writer Jules Verne. This boat attracted special attention and sympathy from the sabotage detachment “K” specially created in the German fleet. Members of this squad are accustomed to evaluate military equipment from the point of view of its combat use behind the front line of the enemy, so they could not but like this machine.
Turtle (also called American Turtle) was the world’s first submersible vessel with a documented record of use in combat. It was built in 1775 by American David Bushnell as a means of attaching explosive charges to ships in a harbor, for use against Royal Navy vessels occupying American harbors during the American Revolutionary War.
