Borei Class Submarine

The Borei class, alternate transliteration Borey, Russian designation Project 955 Borei and Project 955A Borei-A (Russian: Борей, lit.Boreas‘, NATO reporting name Dolgorukiy), are a series of nuclear-powered ballistic missile submarines being constructed by Sevmash for the Russian Navy. The class is projected to replace the Soviet-era Delta IIIDelta IV and Typhoon classes in Russian Navy service. More info from wikipedia(opens in new tab).

My 3d model

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.

Leyland-Levend Public Bus

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.

Robot Vacuum Mini Round

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) 3d model

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. 

Nautilus being launched

Sharing a name with Captain Nemo‘s fictional submarine in Jules Verne‘s classic 1870 science fiction novel Twenty Thousand Leagues Under the Sea[8] and the USS Nautilus (SS-168) that served with distinction in World War II,[9] the new nuclear-powered Nautilus was authorized in 1951. Construction began in 1952, and the boat was launched in January 1954, sponsored by Mamie EisenhowerFirst Lady of the United States, wife of 34th President Dwight D. Eisenhower; it was commissioned the following September into the United States NavyNautilus was delivered to the Navy in 1955.

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.

Nautilus was decommissioned in 1980 and designated a National Historic Landmark in 1982. The submarine has been preserved as a museum ship at the Submarine Force Library and Museum in Groton, Connecticut, where the vessel receives around 250,000 visitors per year. More info on Wikipedia.
