 Bobblerz... just &apos;Bobble&apos;. Very likeable little things (that are quick and easy to print) and bring a smile to your face every time you tap them down onto a sold surface (keep holding the body) and watch them... bobble.
They&apos;re a fun little head that bobbles up / down / sideways on an internally printed spring. Just give your Bobbler a shake and watch it &apos;bobble&apos;...just like watching a fidget spinner spin!
Everyone that sees them likes them and most want one... so they make great little gifts... and as they require just 16 - 18gm filament at standard scale (....and yes they can be uniformly scaled up okay to a certain extent) they aren&apos;t expensive to print.
A range of Bobblerz .stl&apos;s is provided... choose your favourite (refer to images to see the selection) or print them all and create a family of &apos;Bobblerz&apos;. You can even get creative with them by painting the eyes and mouth or pausing your machine mid-print and swapping the filament so you have your own unique Bobbler/z.
Bobblerz are easy to use / have fun with. Just hold the body part then tap them down onto a solid surface, hold them down and don&apos;t let go. This makes them &apos;bobble&apos; best... if you let go much of the energy is lost into the body through vibration so they don&apos;t &apos;bobble as well or for as long. The body part is important as it provides a holding mechanism independent of the internal spring but also limits the sideways spring movement minimizing the chance of breaking them (...because PLA is very brittle).
Competed prints will have four fine bridges which have been designed in to stop the Bobblerz from bobbling during printing... as that would cause all sorts of print issues. These bridges run from the top of the body inwards to the neck section. They should be quick and easy to snap away to leave your &apos;Bobblerz&apos; free to bobble... have fun with them!
You can also add colour the facial features to make them stand out more. If you decide to do this using an enamel paint and very fine brush is recommended. Felt tip pens and acrylic paints are more prone to running / smearing.
These are all easy prints on accurate / precise well set up machines. However, do not use any automated support or you are likely to end up with a spring that isn&apos;t springy so a Bobbler that doesn&apos;t bobble.
Please refer to the print settings and images for additional information... and post images of all your &apos;Bobblerz&apos; for other members to see.

Type of education: 
Elementary school

Number of students: 
Annually an average of 150 pupils attend the course distributed in 15 groups

Duration of the project: 
We plan the project lasts at least 8 years.

Related subjects: 
The world around us, Nature and society, Mathematics

Project description: 
In the next year, mankind will mark 280 years since the death of Sir Isaac Newton, scientists who laid the 
foundation for understanding the world around us. Newton&apos;s laws of motion are three physical laws that, 
together, laid the foundation for classical mechanics. They describe the relationship between a body and 
the forces acting upon it, and its motion in response to those forces. They have been expressed in several 
different ways, over nearly three centuries, and can be summarized as follows. 
First law: In an inertial reference frame, an object either remains at rest or continues to move at a constant 
velocity, unless acted upon by a net force. 
Second law: In an inertial reference frame, the vector sum of the forces F on an object is equal to the 
mass m of that object multiplied by the acceleration a of the object: F = ma. 
Third law: When one body exerts a force on a second body, the second body simultaneously exerts a 
force equal in magnitude and opposite in direction on the first body. 
Using 3D printed parts, pupils construct water or heat-propelled engines from soft drink cans and other 
thing in everyday use. They test the engines and the variables that affect the action-reaction of the 
engines. We will make at least the following three experiments: 
Pop Can 

&#x201C;Hero Engine&#x201D; 
Small pupils teams will construct water propelled engines out of soft drink cans and investigate ways to 
increase the action-reaction thrust produced by water shooting out of holes punched in the can sides.

This activity simulates the operation of the classic aleoliphile engine invented by Hero of Alexandria more 
than 2,000 years ago. Hero&#x2019;s engine was a spinning copper sphere that was propelled by a thrust 
produced by a jet of steam. The engine was an early demonstration of the action-reaction principle (third 
law of motion). Steam, shooting out through two L-shaped holes, creates an action force that is 
accompanied by an equal reaction force in the opposite direction. 
In this activity, a Hero engine-like device is created by the pupils. Holes are punched in the side of a soft 
drink can. The holes are angled pinwheel fashion. A string, tied to the pull tab, supports the can and 
permits it to rotate. The can is immersed in water and pulled out. Gravity draws the water through the 
angled holes, and streams shoot out in either a clockwise or counterclockwise direction. The streams 
produce an action force that is accompanied by a reaction force. The can spins in the opposite direction. 
Part of which will contain nozzles we will make using 3D printing. We will vary the construction and mass 
of part contain nozzles, nozzles, ... Different designs will be evaluated by actual number per minute.

Hero&apos;s steam engine 
This is heated variant of previous engine. Heat to generate the steam had to be applied externally. As 
the water heats up, the molecules of water move faster. When the water boils, the molecules are moving 
too fast to stay stuck together as a liquid, and they move about freely as steam. The fast moving water 
molecules are bouncing around in the can, hitting the walls of the can from all directions. Because they 
hit the top as often as they hit the bottom, the can neither moves up nor down.

But there is one direction in which the molecules don&apos;t hit anything. This is the direction where the holes 
in the tubes are. Instead of hitting a wall of the can, the molecules hit nothing, and exit out into the air. 
The molecules in the can are pushing on all the walls the same amount, except where the holes are. 
Because nothing is pushing in that direction, there is nothing to hold the can back, and it moves away 
from the holes in the tubes. When the fast moving molecules of steam leave the nozzles, they spread 
out in all directions as they run into the slow moving air molecules outside the can. What you feel with 
your hand is the steam molecules that have slowed down in the air, and the air molecules they bumped 
into and caused to move. Not only have they slowed down by the time they hit your hand, but they have 
spread out so they don&apos;t all hit the same place. The combination of moving slowly and spreading out 
makes them feel cool on your hand. 
Rockets and jets move the same way. A rocket can work in outer space because it does not need to 
push against air or the ground. It works because the molecules inside the rocket are pushing in every 
direction except out the back. Our steam engine works because it has two rockets (the brass tubes) 
pushing the sides of the can in opposite directions, causing it to spin. 
Part of which will contain nozzles we will make using 3D printing. A special challenge to the students will 
be connecting hot and printed parts. We will vary the construction and mass of part contain nozzles, 
nozzles ... Different designs will be evaluated by actual number per minute.

Steam powered boat The boat is a plastic recycled bottle cut in half lengthwise or 3D printed body shell. Near the bow of the boat is a small candle. The aluminum cup keeps the melted wax in place, so the boat can go for hours. Small amount of sticky tape is used to keep it in place. The engine is made of 1/8 inch soft copper tubing normally used in refrigerators. The copper tubes must be full of water, and both open ends must be under water. The easy way to fill the tubes is to hold one end under water, and suck on the other end. When the tubes are full of water, and the boat is resting in the water with both ends of the tubing under the water, light the candle. When the coil of copper tubing is hot enough to boil the water inside, the boat will jerk ahead suddenly, then start moving evenly forward. Water in tubes little pulses, about 5 or 10 pulses 
per second. These pulses are pushing the boat along. The holes in the soft plastic will close around the tubing, forming a water-tight fit. At the ends of copper pipes will be mounted 3D printed nozzles. A special challenge to the students will be connecting hot and printed parts. We will vary the construction and mass of the vehicle, engine design, the shape of nozzles ... Different designs will be evaluated by velocity (the time required to cross certain path).

Balloon powered vehicles We will build a small vehicles that will run with compressed air from a balloon using various materials, mainly used packaging. We will vary the mass of the vehicle, the pressure in the balloon, the shape of nozzles ... Using 3D printing we will get coupling elements, nozzles ... Different designs will be evaluated by velocity (the time required to cross certain path).

Learning goals: 
Formation of elementary scientific concepts of natural sciences, 
&#xF0B7; learning initial techniques of cognitive processes: observation, spotting, comparing, classifying, appointment, 
&#xF0B7; encouraging children&apos;s interest, questions, ideas and responses in relation to phenomena, processes and situations in their encirclement in accordance with their cognitive development capabilities, 
 &#xF0B7; fostering and developing research activities for children, 
&#xF0B7; encouraging to observe simple cause-effect relationship, phenomenon and process, free to voice their observations and predictions, 
&#xF0B7; solving the simple problem-situation through experiments on the team,

This CO2-powered crash test car lets you design and iterate crumple zone bumpers in order to protect a passenger egg from injury. Use a CO2 car launcher from someone like Pitsco or Kelvin, wheels from a Lego Technic motorcycle (I got mine on eBay), and create a flat wall for the car to crash into (I put a board against paint cans). The car is guided by monofilament, and I put the wood wall at 50&apos; from the launcher. At that distance, a 12 gram CO2 cartridge will shoot the car fast enough to break an egg without a well-designed crumple zone. Use a slo-motion camera app to capture and analyze the destruction. See &quot;CO2-Powered Eggmobile&quot; on YouTube for my 2 min. video. <iframe width="593" height="370" src="//www.youtube.com/embed/liyXWWYGgdg" frameborder="0" allowfullscreen></iframe> My students copied and tinkered &quot;Bumper Posts&quot; in Tinkercad. This way, the connection to the car is consistent and correct, but the crumple zone element is their own invention.

Credited to Pythagoras of Samos, it allows the user to fill the cup with wine up to a certain level. If they fill the cup only to that level, the imbiber may enjoy a drink in peace. If they exhibit gluttony, however, the cup spills its entire contents out of the bottom (onto the lap of the immodest drinker).

With Creative Tools 3D-printable Vega Xmas Star we want to honor the winners of The Nobel Prize in Physics 2014.Without the hard and tenacious work of Isamu Akasaki, Hiroshi Amano and Shuji Nakamura, today we wouldn&apos;t have efficient LED lights or HD flatscreen television sets, computers and mobile devices.The 3D-files for Creative Tools 3D-printable Vega Xmas Star are therefore designed to enclose a standard and commonly available LED light strip.VIDEO<iframe width="593" height="370" src="//www.youtube.com/embed/iPnVJo4_1uo" frameborder="0" allowfullscreen></iframe>FEATURESModular five-pointed star made of 5 identical partsShort segments of 1.75 mm filament hold the parts together (no glue required!)Ventilation holes provide cooling airflowWall-mount included for horizontal or vertical attachmentWall-mount allows cable rotation adjustment to easily align star parallel to wall or window.Adapted for LED strips 8 x 3 x 1000 mm (12 V, 0.5 A).DISCLAIMERWe have successfully used this star with standard low-power LED strips for indoor use. Please refer to the your LED light source manual and follow all safety instructions.PRINT SETTINGSWe recommend 3D-print operators to use transparent PLA plastic filament. Two (2) shells/perimeters are sufficient for strength. For faster prints &#x201C;rough&#x201D; resolution at 0.3 or 0.4 can be used and there is no need for infill. You can print at zero (0) percent infill. Turn off support structures. The top section of the star segments are closed automatically via &#x201C;bridging&#x201D;. These settings are for filament-based FFF-3D-printers only.MATERIAL CONSUMPTIONRoughly 70 grams of filament in total. Since the design does not need support structures, no material is wasted.MAKE IT IN COLOUR!You can 3D-print in different plastic filament colours. The modular tips of the star also allow for variations in colour per tip. Colour variations can also be achieved by using LED light strips with an RGB colour control.About this year&#x2019;s Nobel Prize in Physics<a href="http://www.nobelprize.org/nobel_prizes/physics/laureates/2014/" rel="external">http://www.nobelprize.org/nobel_prizes/physics/laureates/2014/</a> Creative Tools - <a href="http://Creative-Tools.com" rel="external">http://Creative-Tools.com</a> - <a href="http://google.com/+CreativetoolsSe" rel="external">http://google.com/+CreativetoolsSe</a> - <a href="http://twitter.com/CreativeTools" rel="external">http://twitter.com/CreativeTools</a> - <a href="http://facebook.com/creativetools" rel="external">http://facebook.com/creativetools</a> - <a href="http://youtube.com/creativetools" rel="external">http://youtube.com/creativetools</a> - <a href="http://instructables.com/member/CreativeTools" rel="external">http://instructables.com/member/CreativeTools</a> - <a href="http://instagram.com/creative_tools" rel="external">http://instagram.com/creative_tools</a>

I took a JPEG of the Make logo and traced it in Solidworks... I then extruded and filleted the robot and saved it as its own STL to be used in dual extrusion... I then designed a plate around therobot, added holes for screws and save that as its own STL... Lastly, I design a shell to go around the plate and robot, the shell has aligned screw holes so it can be fastened to the plate...I then printed the shell in regular ole black PLA on my Rep 2...
