Tinkercad is a free online 3D modeling tool that allows users to create and design 3D objects using a simple and intuitive interface. With its block-based approach, Tinkercad makes it easy for beginners to get started with 3D modeling, while still providing advanced features for more experienced users. In this tutorial, we will learn how to design crab legs on Tinkercad, a fun and creative project that will help you improve your 3D modeling skills.

Getting Started with Tinkercad

Before we start designing our crab legs, let’s take a look at the Tinkercad interface and get familiar with the tools and features we will be using.

  • Workspace: The workspace is the main area where you will be designing your 3D model. It’s divided into three main parts: the grid, the toolbar, and the inspector.
  • Grid: The grid is a 3D coordinate system that helps you align and position your shapes. You can adjust the grid size and unit of measurement to suit your needs.
  • Toolbar: The toolbar is where you will find all the tools and shapes you need to create your 3D model. It includes basic shapes like cubes, cylinders, and spheres, as well as more advanced tools like extrusions and holes.
  • Inspector: The inspector is a panel that displays information about the selected shape or object. You can use it to adjust properties like size, position, and rotation.

Now that we have a basic understanding of the Tinkercad interface, let’s start designing our crab leg. We will break down the design into several steps, making it easy to follow along.

Step 1: Create the Basic Shape

  • Start by creating a new project in Tinkercad. Click on the “Create” button to start a new design.
  • In the toolbar, select the “Cube” shape and drag it onto the workspace.
  • Resize the cube to a width of 20mm, a length of 30mm, and a height of 10mm. You can do this by adjusting the values in the inspector.

Step 2: Add the Joint

  • Select the “Cylinder” shape and drag it onto the workspace.
  • Position the cylinder at one end of the cube, aligned with the center of the cube.
  • Resize the cylinder to a diameter of 10mm and a height of 10mm.
  • Use the “Hole” tool to create a hole in the center of the cylinder. This will help us create a joint for the crab leg.

Step 3: Add the Claw

  • Select the “Sphere” shape and drag it onto the workspace.
  • Position the sphere at the end of the cylinder, aligned with the center of the cylinder.
  • Resize the sphere to a diameter of 15mm.
  • Use the “Extrusion” tool to create a small extrusion from the sphere. This will help us create the claw.

Step 4: Add the Details

  • Use the “Text” tool to add some details to the crab leg. You can add lines, curves, or even text to create a more realistic design.
  • Experiment with different shapes and tools to add more details to the crab leg.

Assembling the Crab Legs

Now that we have designed the individual crab leg, let’s assemble them to create a complete crab model.

Step 1: Create Multiple Legs

  • Duplicate the crab leg design by clicking on the “Duplicate” button in the toolbar.
  • Create multiple legs and position them around a central axis. You can use the “Rotate” tool to adjust the position and angle of each leg.

Step 2: Add the Body

  • Use the “Cube” shape to create a body for the crab. Resize it to a width of 50mm, a length of 50mm, and a height of 20mm.
  • Position the body at the center of the legs, aligned with the axis.

Step 3: Add the Eyes and Antennae

  • Use the “Sphere” shape to create eyes for the crab. Resize them to a diameter of 5mm and position them on either side of the body.
  • Use the “Cylinder” shape to create antennae for the crab. Resize them to a diameter of 2mm and a height of 10mm. Position them on top of the body.

Exporting and Printing the Crab Model
