How to 3D Model a Stencil in SelfCAD
A stencil is a simple tool that lets you paint or draw the same shape many times. Stencils are used for art, signs, school projects, decorations, and more. Making stencils by hand can be slow. With 3D modeling, you can design a stencil that is precise, repeatable, and easy to print. In this article you will learn how to import a profile into SelfCAD and use it to make a summer-themed stencil. A profile is a 2D outline or shape that you use to build a 3D model. We will use profiles like a sun, a palm tree, among others, to create a summer stencil. You can check out the interactive tutorial to learn how to design.
In summary, start by launching SelfCAD and open the workspace:
Select the Rectangle sketch tool and click on the green point to start sketching:
Draw the rectangle as shown and then click “X” to close the panel:
Select the Move tool from the toolbar and choose Center Object:
Select the Fillet tool from the Modify category:
Set the Intensity to 5 and the Level to 4. Tick the check mark to finalize the fillet:
On the top toolbar, choose Import from the Files:
Click Load Objects from the Tutorials:
Select all the imported objects on the workspace:
On the top toolbar, on Edit category select Merge:
Select the Extrusion tool from the Modify category:
Set the Extrusion Amount to 2 and tick the check mark to finalize extrusion:
Set the Extrusion Amount to 2 and tick the check mark to finalize extrusion:
Give the stencil an Orange color from the Color Picker:
The single summer themed stencil is now ready:
Applications of the Summer Stencil
In classrooms, students can use it for art lessons, painting summer-themed posters, or decorating walls and projects. Schools can use stencils to make event decorations or name tags. For 3D enthusiasts, it’s a good exercise in mastering importing, cutting, and printing techniques. It also builds a strong foundation for more advanced projects like custom signage, pattern templates, or even brand logos. Beyond education, this kind of project shows how 3D modeling can support creativity, craft-making, and entrepreneurship. Students can design custom stencils and sell them online or in local craft markets. This turns classroom learning into practical experience and opens new opportunities in design-related careers.
How Educators Can Integrate This Project into Teaching
This summer stencil project can fit perfectly into STEM, art, or technology classes. Teachers can divide the activity into stages that match lesson goals: introducing 3D design principles, exploring geometry, teaching about file formats, and understanding digital manufacturing processes. It encourages teamwork, as students can collaborate in groups to design different stencil themes like nature, holidays, or abstract art.
In art and design classes, it promotes visual creativity and precision. In science or technology lessons, it demonstrates practical design application and manufacturing workflow. Schools that adopt 3D modeling as part of their curriculum help prepare students for future digital industries, where such skills are highly valued.
Enjoy powerful modeling, rendering, and 3D printing tools without the steep learning curve.
