3D Modeling an Egg Holder in a SelfCAD

Introduction:

In this tutorial, we are using two main tools of SelfCAD: Spiral generator and Sphere. We will also use 3D-Sketch, Scale, Move, and Inverse tools to make the combined object of the Egg Holder. The Spiral generator tool helps to give us the exact shape of a spiral in the way we want. This tutorial will basically guide you to know more about using Spirals and Modifying them in 3D modeling software. 

The 3D Shape Sphere tool is used to create the Egg shape, and that will be the easiest part of the tutorial or most manageable object in this 3D Model of Egg Holder. 

So, let’s get going!

Step 1: Creating Spiral to make the Egg Holder

We are creating the spiral with an Egg Holder. For that, we will start creating the Spiral. Choose Spiral Generator from 3D-Shape Category of Toolbar (G+P).

Set the Top Radius parameters to 20, Height to 150, edges to 1. It is also possible to set the revolves, and instead of making a circle, you can make it a zigzag.  Finalize the Spiral generator.

We will now create the holder. The shape must be proper so that it holds the egg correctly. So we are creating several Spirals. Activate Spiral Generator from 3D-Shape Category of Toolbar (G+P). Set the Parameters: Set Bottom Radius to 20, Height to 200, edges to 1, Position Y to 150.   Finalize the Spiral generator and we will have the 3D design shown below.

Using the spiral generators again, set the following Parameters: Top Radius to 50, Height to 100, edges to 1, Position Y to 350.  Finalize the Spiral generator.

 

Select Spiral_1 again and deselect spiral_3 by clicking on it.

Step 2: Use Rotate and Move To Change Angle and Position

Next, we will Rotate the spiral as required. So we have selected spiral_1. Now, choose Rotate. Set Y to 10, and close it. 

Select the Move tool from the toolbar and set x to 0.3, as shown in the 3D design below. 

Step 3: Modifying the Spiral

Next, with the scale tool, we will modify the bottom of the holder’s base. Once you have clicked on the tool, set y to 20 using the highlighted gizmo. 

Select Spiral_2, spiral_3 to select it, and spiral_1 to deselect it. Choose the Scale and set y to 80. Next, we modify the top spirals. 

As you can see, we got the needed shape but are away from each other. For that, we will be using the Move Tool to combine both the spirals to get the perfect shape. Select the Move tool and Set x yo 20, and we will get the 3D design shown below.

Select Spiral_1 and from the Utility category, choose Merge (U+E). 

We have created the object, but it is just a wire that we can see. We’ve created the structure. Now, we need to make it in 3D. 

Step 4: Create 3D-Sketch of Spiral Holder

Activate 3D-Sketch from the Drawing category. And from the Tool Panel, choose Circle (K+C) and draw it.

Select the Spiral_1 and Copy: Choose Follow Path in the Tool category in Toolbar (T+P). Finalize the Follow Path. 

Select the 3D design: Deselect the mesh_1 by clicking on it. Select the move tool and Set y to 20, and close the transformation panel. 

Step 5: Converting objects into a single object

Select the mesh_1 by clicking on it. Choose the Stitch & Scoop and select Union (B+U). Finalize the Union. With Union, we combine the object and it makes the Union and creates a single object.

Choose the Inverse Selection to invert the 3D design.

 

Next, we will delete the selected object. We deleted just the profile path that we created while creating 3D Sketch. 

Step 6: Creating the Egg Shape

Next, we will create the Egg Shape:

Activate Sphere from the basic shapes. With the help of parameters, we will modify the sphere shape in the egg. Set Radius to 40, Position Y to 50. Finalize the Sphere.

We shall continue 3D designing the model by choosing the scale and setting the Y value to 100. Finalize the Scale.

Thus, we have created the Egg Holder.  

Observations:

This tutorial has covered the basic tools of SelfCAD like the Spiral and 3D shape generator and used other vital tools like the scale, move, and 3D Sketch tools. We have repeatedly generated the spiral and modified it into a single Egg holder.  All the 3D models created in SelfCAD are 3D printable as they leave no geometric errors that could make the designs hard to print. 

Once done with the design process, you can use the in-built slicer of SelfCAD to slice your design and generate the G-Code file that you can send to your 3D printer. All in all, we hope you find the tutorial and the procedure interesting and handy. Let us know your queries and suggestions in the comments section below!
