Repair damaged thread in the nut

Younger students can use the tinkercad program. They will thus become familiar with the basic principle of modeling and the use of threads for construction purposes.

Older students can use the Fusion 360 program, which offers the possibility to change a number of types and parameters when creating threads. They will become familiar with the procedure of accurate measurement and marking of threads. By printing and trying the model, they verify the correctness and functionality of the construction.

The work requires at least basic knowledge of working with a caliper and concepts such as the diameter and height of a cylinder. Furthermore, at least basic knowledge of working with the Tinkercad program such as creating objects, changing dimensions and merging objects is required. At least basic knowledge of 3D printing, such as setting perimeters and filling, is also required.

The main aim of this project is to teach students to recognize individual types and parameters of threads. Using their correct designation and notation. Know how to measure the basic parameters of a thread, create its 3D model for construction purposes. Last but not least, also know how to prepare a model for printing and make a functional part for specific real use. To show the possibility that 3D printing can also be used for the production of spare parts, thereby contributing to saving the environment.

• Computer
• 3D printer
• Caliper

Students to identify the type of thread and measure its main geometric parameters.

Based on the dimensions, create a 3D model. Slice the model correctly and print it.
 

Test the functionality and durability of a printed real product.

The detailed procedure for modeling in Tinkercad and Onshape 360 is in the attached PDF manual.
