I'd like to deliver a message about charging station is not an issue for usage of electric scooter. Recharging battery of your electric scooter at home like filling up a tank of water is easier and cheaper than refill your ICE scooter in gasoline station.

An Electric Scooter Marketing Story
A young man promoted electric scooter to an old man.
The old man refused, "Charging is inconvenient, take a long time, it needs two to three hours once."
A few days later, the young man got an idea, and came back to find the old man.
Young: "Uncle, there is an amazing scooter, free fuel, water only. Are you interested in?"
The old man: "You're kidding. Is it true?"
Young: "However, it needs smaller pipe, drop a little longer, it makes scooter ride more smoothly."
The old man: "How long does it need to drop?"
Young: "almost 2 to 3 hours."
The old man: "Dropping 2 to 3 hours once is fine, that is no difference, water is also cheaper than gasoline. You should have told me earily such a good thing. I might have said I bought one right away..."
Young man show the old man an electric scooter and this faucet charger immediately.

Highly detailed model, 85 cm. high (true 1:400 scale) designed directly from the original blueprints. The model was built from 52 pieces, most of them 3D printed flat and glued together. Some of the pieces need light thermo-forming to adjust the curvature of the assembly and avoid printing with support.
All pieces of the model can be printed in a 20x20 cm. printing bed, but if you have a larger printing bed the model can be scaled up to build a huge and beautiful tower.

Welcome to the Falkirk Wheel in Scotland; the only rotating boat lift in the world. It features Celtic-inspired, double-headed axe arms, which hold two water-filled gondolas to carry boats. It took 8 years to plan, design, and construct between 1994 and 2002. The Falkirk Wheel connects the Forth and Clyde Canal with the Union Canal for the first time since the 1930's when 11 navigation locks were removed.

Hundreds of thousands of people visit the Falkirk Wheel each year and now you can enjoy my approximate 1/500 scale model from your 3D printer.

Design:
Using Blender alongside photos of the wheel that I found online, I modeled a moveable assembly composed of 17 printable parts. I took care to ensure that all parts could be simply printed without supports and assembled without additional connecting hardware. All that is needed is a 3D printer and filament.

The rotating arms hold gondolas that maintain an upright position using gravity. The model is spun by hand by pushing on the arms, or twisting the knurled shaft stub that extends through the back support. This shaft has the ability to be modified for a gear reduced drive. A worm drive modification in the downloads contains replacement parts for adding a stepper motor.

The boat is powered by steam, using a candle to boil water in a “boiler.” The water boils, thus expanding into steam, and this expanded steam pushes water that is in the exhaust (plastic straws), causing the boat to move about the water. Then when the water cools down, it creates a vacuum which sucks more water into the exhaust, thus creating a cycle that repeats itself. While this process is occurring there is a very clear popping sound created, thus the name “Pop Pop Boat” is quite fitting.

This is a handy tool to remove annoying tics from your pet. Grab the tic by sliding the two arms around it until it get gripped well, then rotate the handle with your fingers and the tic lets got quite easy. Normally I have been removing tics with my fingers but it is very hard to get all of the tic out and this could lead to inflammations.

Finally, be the star of commuter traffic! Make all the kids in the neighbourhood happy! Or just jealous! Engage in inspiring discussions with chemtrail believers! With the wind-driven Bicycle Bubble Machine drawing a dense stream of soap bubbles behind you, you too can bring peace and happiness back to the streets!

The Bicycle Bubble Machine is a bubble machine attached to the luggage rack of your bike. I actually found bicycle-mounted bubble machines on the net, but they all run on batteries, neglecting the fact that on our bikes we have a source of energy which is much more sustainable and fun: relative wind. The Bicycle Bubble Machine only uses the relative wind created by riding your bicycle: a wind wheel will turn a wheel with bubble wands, which are blown directly by the relative wind. It works surprisingly well at a comfortable range of speeds, and with the funny, jet-engine look the machines have, when one is attached to every side of your bike, it's an eyecatcher. Well, at least it gave me a lot of strange looks when using it on the street.

This is my first real project constructing something which moves. While I'm not an engineer (so please be kind!) I did put a lot of work in this (and printed lots of prototypes ...): for example the tank was supposed to be printable in one piece, store enough liquid, not store too much liquid in 'dead' places, and not spill all the time while cycling. The design now for example has bulkhead walls to reduce sloshing effects. That said: it will still get messy, but that's part of the fun :)

While I thought about a gear system, I discarded this idea, because everything I could come up with led to a) a smaller tank, b) larger dead spaces of fluid, c) too many wind turbulences in the bubble path etc. If you're interested, I've written about the process of designing this here

This thing is not difficult to build. I tried to give detailed instructions.

Future improvements might be: a lever to temporarily block the bubble wheel, so you can turn off the machine when it is not needed; and modifications to the bubble wheel like combining two bubble rings to a long one for larger bubbles, or improving the topography of the bubble rings to store more fluid.

For the pulleys, I used Parametric Pulley by droftarts. I kept them although I dropped using tooth belts (replacing it with elastic ribbon), because they give good friction.

Please take a look at these remixes: http://www.thingiverse.com/thing:976106, http://www.thingiverse.com/thing:973210 and http://www.thingiverse.com/thing:1656828. They definitely make this design better; miroks tank prints easier and without difficult removing of support (his bubble wheel makes more bubbles and might print better on printers with problematic bed adhesion, but for you it might also lead to many connected bubbles which don't fly as good, as someone reported); 3dMODler's remix will help those with friction problems on the pulleys. The third one by jkf123 is a clever idea to reduce spilling even further, by collecting spilled liquid and leading it back to the tank again.

Wind Energy Stored In Gravity

The challenge

Design a 3D model that harnesses the power of the wind.

Technology connections

Energy transfer, movable assemblies.

The idea

This model demonstrates a fairly new idea that is being used in the field of renewable energy:

Storing energy from wind and solar in gravity. This simple solution eliminates the need for expensive and environmentally unfriendly batteries.

We can use generated energy to lift heavy objects and later retrieve the energy using the weight of the lifted object to turn gears on its way back down. A gravity battery is considered full when the heavy object is lifted all the way up.

Real world implementations of this concept usually involve weights that are either lowered into deep holes in the ground or held in above ground silos.

How it works

Energy is generated using a vertical wind turbine on the lefthand side. There is a movable battery section in the middle that can be adjusted left or right to charge or expend the gravity battery. On the right side, there is a fan that can be used to reproduce the summer breeze after it is caught and stored in the battery.

Multiple copies of the rack gear can be glued together to increase the storage capacity of the battery indefinitely. There is a small release lever on the top left of the movable battery area that keeps the gears moving in one direction.

It may not be an exact replica, but it looks very similar, and it spins really fast and without effort just by blowing to it.

I used solidworks and a lot of mathematics from archimedes to design it.

I added the STL files and the solidworks files, i printed them in a .3 scale. and the size is the one in the video.

update-2/10/2017- added a half hull model file suitable for printing or CNC

I was cruising around on Thingiverse and noticed the STEAM challenges, particularly #makeitfloat. After just a few minutes reading about the contest, I knew exactly what I was going to design and print and how to integrate the STEAM requirements!

I love the romance of wooden sailboats. They are a wonderful marriage of art and science. Each one crafted by a maker's hands, its design influenced by the scientific interaction of wind, wood, and water. It's so cool that a mathematically and aesthetically beautiful shape are the same thing!

There is a small sailboat I have always wanted to build for myself. The Herreshoff 12 1/2-footer, designed by "The Wizard of Bristol" N.G Herreshoff and first built in 1914. Over time, this boat has assumed archetype status in the field of small wooden sailboat designs. It inspired Joel White, a modern naval designer, to develop a version with a retractable centerboard, the Haven 12 1/2. Mr. White's willingness to combine historic and modern design inspired a new generation of 12 1/2 makers to build them using modern techniques and materials, while staying true to Herreshoff's charming daysailer lines. Thanks to inspiration from the #makeitfloat challenge, I decided to put a Maker's twist on history using modern desktop 3D design and printing methods.

Working from found images only, I began reconstructing the Mini-me version of the Haven in my 3d design software. Not surprisingly, I had to revise parts and design details to accommodate the size, printability, and purpose for which my design was intended, a sort-a-scale model, not a sailboat for 4 adults. Once the virtual model was complete, I added in the Makerbot logo as a finishing touch, swapped the fraction for a decimal, and christened this vessel, Maker 12.5 in tribute to its heritage. A bit of old, a splash of new, and a sprinkle of Makerdust!

In addition, there is a nautical science aspect using coinage that can be demonstrated with this model using the 12 1/2 foot load waterline length (LWL) measurement that gives the craft half its name. I have split this model at the LWL to make the line obvious and for ease of printing. With that in mind.... PREPARE FOR SCIENCE!

The waterline is often indicated by a stripe or color change down the broad side of the hull. It serves as a visual reference to the trim of the boat in the water. A naval architect computes the weight of the boat and its gear, passengers, and cargo and integrates that information into the hull design to generate the LWL line. Although a waterline can be any line where the hull intersects the water, the LWL is a special line that indicates where the boat will float before it starts to use up its reserve buoyancy. It can also show if the boat has its weight distributed properly fore (to the front) and aft (to the rear) as well as port (left facing forward) and starboard (right facing forward).

As the boat sinks in, the hull displaces the water according to the volume of its hull below the waterline. The term displacement, in this instance, refers to the weight of the water shoved out of the way by the hull. By changing the amount and distribution of the weight around the inside of the boat, we can compare the waterline at sea level with the LWL line on the hull to help make decisions about how the boat is loaded.

Now that you know some nautical history and science, your challenge is to print this little boaty beauty and find the answer to this question: How many quarters does it take to ballast this design at the LWL as designed by the naval architect?

I theorized that it would not take much weight, but I was concerned that it might not float at all! Nonetheless, I started filling the sink for testing. I did have some small hurdles to deal with that did not become evident until testing. The main issue was knowing that due to the sparse infill, this design was not watertight and would gradually flood with water, affecting the test. I solved that issue by applying a thin layer of plastic wrap over the hull. The second was that the model was biased toward one side due to the angle of the sail rig, so I had to compensate by offsetting the ballast to the side. Once those problems were worked out, I started loading quarters and arranging them to find the answer to my question for the #makeitfloat challenge.

So, how did it turn out? Check the pictures above for the results. I had already tinted the hull, so I used a thin layer of plastic wrap on it to keep the color from bleeding while it was in the water. The first test result pic shows the Maker 12.5 with the quarters in place and the second shows the results at the waterline when ballasted.

More info is on the instructions page. I also wrote an article for 3dprint.com about the process, giving Thingiverse a shout out. http://3dprint.com/81733/3d-printed-dailboat/

My purpose to design a mini USB vacuum cleaner was the consequence of the mess I was confronted to, after making stuff for hours with plastic, wood, and electronic parts on my desk.

I needed a small and efficient device to clean the mess, so I decided to design and make my own.

This mini vacuum cleaner is very helpful ! I can now easily clean my laptop keyboard, my desk, and all the small fragile items I collect.
