  • While printing the design, the printer should be checked periodically.
  • It should be noted that the temperature settings of the printer are adjusted according to the type of filament used.
  • Since the printer works at high temperatures, the printer should not be interfered with during operation.
  • If intervention is necessary, it should be under surveillance.
  • After the assembly, the codes of the project may need to be changed according to the position of the servo motor.
  • If the servo motor cable needs to be extended, jumper cable can be used.
  • A new part can be designed to be able to press the button more easily.
  • Double-sided tape can be used to fix the button to the ground.


Water Control
To find out how your school uses water, how much water is used and how you can reduce it:

  • Students can be divided into teams to walk around the school counting and listing everything that uses water.
  • Students can research how much water each device uses and brainstorm ideas to reduce it.
  • All results are put together in tables and graphs and/or on a poster.
  • If possible, the created posters can be displayed on the school boards.
  • An example of a school related to the studies carried out on water consumption can be viewed at the link below.
  • The following website can be examined to raise awareness about the conscious consumption of water.

  • - Students can observe how much water they use in daily life. They can research technological systems that reduce water consumption on how to control this.
HOME TASK 2: With the project realized as a result of the engineering and design course, students are asked to calculate their daily water consumption.
The result is compared with the results from home task 1.
Banners, posters, etc., in order to raise awareness of the results. it can be made to benefit from the school and those around it.
Finally, the following statistical example can be presented to students.
The daily amount of drinking and utility water per person for the cities of Istanbul, Ankara and Izmir in 2018 by the Turkish Statistical Institute was calculated as 224 liters.

PART 3

Students' Prior Knowledge About 3D Design

Divide the class into pairs or small groups, give each group a worksheet, ask the following questions:

- What is 3 dimensions? What is the difference between 2 and 3 dimensions?

- Have you done 3D design before? If so, what programs did you use?

- What is a 3D printer? What can be done with 3D printers?

Collect and display the answers on one page. Check and discuss the topic.

You can show a movie about 3D printers.

Making the Design

Let's design an apparatus from a 3D printer on the knob of our faucet for the Arduino project we did in the engineering class.

  • First, the size of the knob of the tap is measured with the help of a ruler and a note is taken.

Visual 1


Visual 2

  • Since the size and shape of the knob of each faucet may be different, designs are made according to the imagination and design skills of the students.
  • After the measurements are taken, the Tinkercad program is opened for 3D design.
  • While designing, it is designed a few mm larger than the predetermined dimensions. The design needs to fit on top of the bun.

Visual 3

  • After the design is completed, it is saved to the computer in .stl extension with the export design option.
  • The downloaded design is transferred to the slicing program and slicing is performed according to the need.

Visual 4

  • The 3D printing process is started using a 3d printer
  • The printer is checked during printing. In particular, the printer is observed until the ground layer is printed properly.

  • The design that we started in the part 2 is carefully taken from the printer after the printer has cooled down.
  • The burrs on the edge of the design are removed using sandpaper

Visual 6


The print we designed with the servo motor apparatus is adhered. While sticking, care should be taken to stick to the very center.

  • Fast adhesive or hot silicone can be preferred while bonding

Visual 7


The prepared part is attached to the servo motor.

Visual 8


  • The piece is attached to the knob of the faucet as in the image.

Visual 9


  • A piece is placed between the servo motor and the sink to fix the servo motor. This piece can be designed and printed on a 3D printer if desired.
  • Make sure that the piece adheres well to the floor. You can use hot glueto stick it to the floor.

Visual 10


  • And our project is ready! When we press the button, the servo motor turns and makes the water flow. When we take our foot off the button, the servo motor returns to its initial position and prevents water from flowing.

Explaining the project

What does the project aim for, what will it test and how will it be executed?


We have once again understood the importance of our hand hygiene due to the corona virus. To get rid of the corona virus completely, we need to wash our hands with soap for 20 seconds, and during this time the water continues to flow. Thanks to our project, water continues to flow only while washing our hands, so we save water.


In our project, we have controlled the water that will flow from the fountain by using a servo motor. When we press the button with our foot, the servo motor will turn and open the tap. When we take our hand off the button, the servo motor will return to its initial position and our tap will be closed.


Thanks to the project created, water will be saved by ensuring that the water flowing from the fountain flows in a controlled manner.
