How to Build a Chain in Tinkercad

Tinkercad is a popular online platform for 3D design that allows users to create and model various objects easily. One exciting project you can undertake is building a chain. This guide will provide you with a detailed, step-by-step process to create an interlinked chain in Tinkercad, essentially enriching your design skills while bringing your ideas to life.

Getting Started with Tinkercad

Before diving into the creation of the chain, make sure you have a Tinkercad account set up. Navigate to the Tinkercad website and log in. If you’re new to the platform, creating an account is straightforward and free of charge. Familiarize yourself with the Tinkercad interface, including the workplane, shape tools, and navigation controls.

Setting Up the Workplane

Once you’re logged in, create a new design by clicking on the "Create New Design" button. This opens a blank workplane where your chain will take shape. Adjust the view as necessary to see the entire work area, making it easier to manipulate your shapes.

Designing the Link Shape

The first step in building a chain is to create the link shape. Begin by selecting a basic shape from the right toolbar. The ‘Tube’ shape is an excellent starting point since it resembles a round link.

1. Drag the Tube to the Workplane: From the shape menu, drag the ‘Tube’ onto your workplane.
2. Resizing the Tube: Click on the tube and use the corner handles to resize it to your desired dimensions. A common size for a chain link might have a diameter of about 10 mm and a length of about 20 mm.
3. Adjusting Shape: On the properties menu that appears when you click on the shape, you can also modify its width and height to achieve a more elongated or circular appearance, depending on your design preference.

Duplicating the Links

With one link created and sized, the next step is to duplicate it to create the rest of the chain.

1. Copy and Paste: Select the link, then use Ctrl+C to copy and Ctrl+V to paste it. You can also right-click on the shape and select ‘Duplicate.’
2. Position the Duplicates: Manually drag each duplicate to the side of the original link to create a linear arrangement. Alternatively, you can use the align tool found in the upper right corner to ensure they line up straightly.

Rotating the Links for Connection

To ensure your links connect properly, rotate every alternate link 90 degrees.

1. Select the Link: Click on a duplicate link.
2. Use the Rotation Handles: Click and drag the rotation handle to turn the link to the desired angle. This will allow the links to interconnect as intended.
3. Align with Others: When you adjust the rotation, use the grid and snapping features to ensure precise alignment with the rest of the links.

Merging the Links

Once all links are positioned and rotated correctly, it’s time to merge them into a single, continuous chain.

1. Select All Links: Click and drag to create a selection box around all the links.
2. Group the Shapes: With all links selected, click on the ‘Group’ option in the upper right corner. This effectively creates one single object from your chain links.

Adding Color and Final Touches

Now that your chain is complete as a 3D model, enhance its appearance by adding color.

1. Select the Grouped Chain: Click on the grouped chain to modify its properties.
2. Choose a Color: Access the color options in the right-hand menu and select a color that suits your design.
3. Final Adjustments: You can also add other design elements or embellishments to the chain, depending on your creative vision.

Exporting Your Design

Once satisfied with your chain design, it’s time to export it for printing or sharing.

1. Click on the Export Button: Located in the upper right corner, select ‘Export.’
2. Choose File Format: You can select different formats like .STL or .OBJ based on your needs, particularly if you’re planning to 3D print the design.
