X-Ray Class Submarine

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

Steam Engine Model

steam engine is a heat engine that performs mechanical work using steam as its working fluid. The steam engine uses the force produced by steam pressure to push a piston back and forth inside a cylinder. This pushing force can be transformed, by a connecting rod and crank, into rotational force for work

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.

Zeeteyfel Submarine with tank tracks

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.

SP-350 Denise, Cousteau’s Science Submersible

The SP-350 Denise, famous as the “Diving saucer” (Soucoupe plongeante), is a small submarine designed to hold two people, and is capable of exploring depths of up to 400 metres (1,300 ft). It was invented by Jacques-Yves Cousteau and engineer Jean Mollard at the French Centre for Undersea Research.[1] It was built in the year 1959 and usually operated from Cousteau’s ship, the Calypso.

Type 209-1400 Submarine

The Type 209 is a class of diesel-electric attack submarine developed exclusively for export by Howaldtswerke-Deutsche Werft of Germany. The original variant (Type 209/1100) was designed in the late 1960s. The class is exclusively designed for export market. Despite not being operated by the German Navy, five variants of the class (209/1100, 209/1200, 209/1300, 209/1400 and 209/1500) have been successfully exported to 13 countries, with 61 submarines being built and commissioned between 1971 and 2008.

Mırmır Electric Vehicle

Mırmır is a tadpole trike

It is the design that won me a 3rd prize in a national design competition. This is a new and improved version of Mırmır, which is modified to be a scaled down 3d printable model-toy. It can be push uperated or can be made as a RC car. It has a DC drive motor, ample space for a steering mini servo, independent rubber suspension both at the front and rear. It is a small and funny project.
