This is a mini sized 3d printable mobile robot platform.
the robot travels on a standard 7 spd bicycle chain.
Mobile Robot Platform
Wind turbines for vehicles.
We used to put small propellers on the handlebars of our bicycles when we were kids. Now we got older but we can still do the same thing to our cars or motorbikes. I’ve been designing some toys for big boyz recently.
There are several versions, all stl files are included in the following pages.
two turbines with generatos and leds 
single turbine

Ghost Busters’ PKE Meter.
The P.K.E. Meter (also known as Aurascope) was one of the Ghostbusters’ tools invented by Dr. Egon Spengler that enabled them to track ghosts and other entities.
The full name of the device is a Psychokinetic Energy Meter, so named because its function is to detect the amounts of said energy and to direct the user to its location.
The design of the device is a small screen, mounted on a handle, which has a pair of sensor ‘wings’ protruding from either side. These wings have lights along their length, and will flash and extend as the meter closes in on the source of a P.K.E. signature. Much like a metaphysical Dowsing Rod, the meter will begin to buzz more and more in response to approaching a source of P.K. Energy. Once at the source of the energy, the wings will extend to their fullest length and the meter will buzz noticeably at a higher pitch.
As the name implies, here is a PKE METER design similar to the one in the movie; Ghost Busters. Print this and use it to complete your ghost busters prop set or costume. Being a designer, I’ve improved the design a bit, so this PKE meter is not %100 same with the one in the movie, a bit smaller to fit smaller printers, better buttons and minor changes at the details. Internals should be quite different as i’ve never seen the inside of the original. 😀

Fiat 126 Oil Sump & Rocker Covers.
I’ve modeled these parts to match the dimensions of the original parts.
So the models are 1:1 size.

USS Alligator 3d model
USS Alligator, the fourth United States Navy ship of that name, is the first known U.S. Navy submarine, and was active during the American Civil War (the first American submarine was Turtle during the Revolutionary War, and was operated by the Continental Army, vice Navy, in 1776 against British vessels in New York harbor). During the Civil War the Confederate States Navy would also build their own submarine, H. L. Hunley.
The 3d model was made in Rhinoceros 3d and available for download in Rhino’s 3dm format at the following pages.
Ford T 3d model
The Ford Model T (colloquially known as the “tin Lizzie“, “leaping Lena“, “jitney” or “flivver“) is an automobile produced by Ford Motor Company from October 1, 1908, to May 26, 1927.[10][11] It is generally regarded as the first affordable automobile, which made car travel available to middle-class Americans. The relatively low price was partly the result of Ford’s efficient fabrication, including assembly line production instead of individual handcrafting.[12]
The Ford Model T was named the most influential car of the 20th century in the 1999 Car of the Century competition, ahead of the BMCMini, Citroën DS, and Volkswagen Beetle.[13] Ford’s Model T was successful not only because it provided inexpensive transportation on a massive scale, but also because the car signified innovation for the rising middle class and became a powerful symbol of the United States’ age of modernization.[14] With 15 million sold, it stood eighth on the top-ten list of most sold cars of all time, as of 2012.[15]
