How to Make Fidget Spinner in Tinkercad?

Understanding the Basics of Tinkercad

Tinkercad is an intuitive, web-based 3D design application that allows users to create digital models easily. It is particularly popular among beginners and educators due to its user-friendly interface and accessibility. Familiarizing yourself with the workspace and basic tools of Tinkercad is essential for making your own projects, such as a fidget spinner.

Setting Up Your Project

To begin creating a fidget spinner in Tinkercad, you first need to access the platform. Here are the steps to follow:

1. Create an Account: Go to the Tinkercad website and sign up for a free account if you don’t have one yet.
2. Start a New Project: Once logged in, click the ‘Create New Design’ button. This will open a blank workspace where you can start working on your fidget spinner.

Designing the Spinner Base

The next step is to create the base of the fidget spinner. The base is typically a simple geometric shape. Follow these steps:

1. Select a Shape: From the right-hand side shape panel, choose a cylinder shape and drag it onto the workplane.
2. Resize the Cylinder: Adjust the size of the cylinder to your desired dimensions. A radius of about 15-20mm and a height of around 5-10mm generally works well for most fidget spinners.
3. Create the Center Hole: To allow for a bearing or central mechanism, you will need to add a hole in the center:
   • Drag another, smaller cylinder onto the workplane. This will be used as a hole.
   • Resize it to fit the center of the larger cylinder and position it correctly. Ensure that it is slightly smaller than the center of your spinner base.
4. Use the Hole Tool: Select the smaller cylinder and switch its status to ‘Hole’ from the shape panel. Group the two cylinders to create a hole in the center of the larger base.

Adding Spinner Arms

Now, it’s time to add the arms that will hold the weights of the fidget spinner:

1. Create a New Cylinder: Again, drag a cylinder onto the workplane.
2. Adjust Size and Position: Resize the new cylinder to become one of the spinner arms; a length of about 40mm, width of 10mm, and a height of 5mm would be ideal.
3. Copy and Rotate: Duplicate the arm two times. Position these copies in a radial pattern around the base. Each arm should typically be spaced evenly at 120 degrees apart.
4. Align: Use the align tool to ensure that all arms are positioned correctly around the base. Select all arms and the center base, then click the ‘Align’ icon to center everything appropriately.

Adding Weights for Balance

To improve the functionality and promote smoother spinning, weights can be added at the ends of the arms:

1. Create Spheres: Drag a sphere shape from the shape panel and resize them to fit nicely at the end of each arm (about 5-10mm).

2. Position the Spheres: Place each sphere at the end of each arm. You may need to adjust the height so they sit slightly above the arm to look balanced.

Finalizing Your Design

1. Group the Entire Assembly: Once satisfied with the positioning and design, select all components and click on the ‘Group’ button. This will merge all parts into a single object ready for export.

2. Export Your Design: Click on the ‘Export’ button to save your design. For 3D printing, it is commonly exported in STL format.

3D Printing Your Fidget Spinner

If you want to print your fidget spinner, ensure your design is optimized for 3D printing. Use slicing software to adjust settings according to your 3D printer specifications before printing.

Frequently Asked Questions

What materials are best for printing a fidget spinner?
The most common materials for 3D printing fidget spinners are PLA and ABS plastics, as they offer good strength and durability while being lightweight.

How can I improve the spinning time of my fidget spinner?
To enhance the spinning duration, ensure your spinner is perfectly balanced. Using a lighter material for the base and placing heavier weights at the end of the arms can help achieve this.

Can I customize my fidget spinner design?
Absolutely! Tinkercad allows you to personalize your fidget spinner in many ways. You can modify the shape of the arms, add unique textures, or include personalized engravings for a custom look.
