Designing a basic fidget spinner involves several key steps that require precision and attention to detail. Utilizing the powerful capabilities of FreeCAD software can streamline this process significantly. Firstly, launch the FreeCAD application and create a new project. Next, select the "Part Design" workbench from the toolbar, as it provides the necessary tools for creating 3D models. Create a new sketch by clicking on the "Sketcher Workbench" button in the top-left corner of the screen. Draw two concentric circles to represent the fidget spinner's center and outer rim. Add a few key points to define the shape of the spinner, taking care to maintain symmetry between both sides. Switch back to the Part Design workbench and use the "Pad" tool to extrude the sketch into a 3D object. Apply a small radius to create a smooth edge around the spinner's circumference. Using the "Fillet" tool, add rounded edges to the object, ensuring they are consistent across both sides of the fidget spinner. Next, create two additional parts using the same process: one for the bearings and another for the axle. These components will be essential in enabling smooth rotation of the fidget spinner. Assemble all the parts together, paying close attention to their precise alignment. Finally, export the model as an STL file or other compatible format for 3D printing. The resulting design is a functional fidget spinner with a sleek and modern appearance. Its simplicity belies its effectiveness in providing a fun and engaging experience for users of all ages.
