Push-down button with a ballpoint pen spring

thingiverse

This is a push-Down button consisted of three independent parts (inner, upper outer and lower outer) and a typical ballpoint pen's spring. When parts are combined, button can easily moves and you can push it down. It will revenue back into initial place as soon as released.https://www.youtube.com/watch?v=W45jbWiRs3k Print Settings Printer Brand: Up! Printer: Up Mini Rafts: Yes Supports: No Resolution: 0.2mm Infill: 20% Notes: There will be no need for support if printed in a position shown in the pictures. Post-Printing After printing you may have to rub the inner parts exterior surface with merey. If you don't you may be hard to put to push down button. After parts are get used to each other, it will be very enjoyable action. Use a ball point spring in a 0,4 diameter and 30mm long. How I Designed This upper outer upper outer last lower outer lower outer last inner (button) inner (button) -more inner last Project: Push-down button with a ballpoint pen spring Project Name This is a three piece push button combined with a ball-point pen spring. It can be pushed down and returns to initial position when released thanks to spring. After print, individually designed parts can easily be joined. Students can dissassemble it into orjinal parts whenever they want and reassemble it at once again. Overview & Background Buttons... indispensible for our daily lives. Even touch screens are spreading rapidly, it looks like they will be a part of our lives for a while. There is generally placed a push button for almost every electronic devices and they help us to control them easily. It is important for a student to know a tool's mode of operation best before use it. By completing this project, you will learn how this kind of push buttons work and will develop an understanding of the operating principles of them. Objectives students who participate in this project would be expect to learn, how a button works. how a simple interlocking system can be designed. how to integrate 3D printed plastic with other types of materials (a spring made of aliminium). what is the relationship between button's height and spring's total height. which criterias must be considered to make button pushable. the relationship between the button's push and release movements. how to- design a product efficiently. Audiences 10th grade students and above are appropriate for this project. Subjects Physics (springs), maths, geometry, technology and design, industrial product design. Skills Learned (Standards) By completing this project students will able to; create a circular buttons. align more than one shape to the center of each other transform a cylinder into a tube design a suitible hole to use ball-point pen spring inside the button design seperate parts that can be intertwined easily develop an understanding of how to produce a product more efficiently develop an understanding of how to use a combination of different materials in one product aware of how push buttons work Lesson/Activity To complete this project, first you can tell students to search abour push buttons. Even an example could bring to class and this would provide a fisrt hand information about how push buttons works. Secondly, after a brief data gathering each student could generate an idea, that will help some people or solve any problem with push buttons. Lastly, a deadline may be given them. And after printing, may ask stundets to test prototype in the problem context. So that, product's obstacles and incorrect parts could be detected by student and this will give him an idea of what will be fixed next. Duration It may take 2-3 class hours to complete project. In the first hour, let students generate their own ideas and this will led them to a unique or maybe an innovative push button design in tinkercad. Prepraration Tinkercad is free. You dont need any hard technologies at all. Before project, all students had been shown tinkercad basic commands and alignment functions. And you need a simple ballpoint pen. For each project there must be one spring ready to use. References Before project, teacher or students may have review push button's functionality and mode of operation. Rubric and assessment Students should have designed a three pieces push button at the end of the project. Parts should be printed seperately. Printed parts must be good shaped and inner part should be move inside the outer part up and down frictionlessly. In order to combine with a typical spring, spring must be fit smoothly both upper and lower parts
