Angles are abstract — until you can manipulate them.

This hands-on STEM kit lets you explore angles visually and physically — from simple acute angles to full 360° rotations. Instead of memorizing values, one can see and feel how angles behave.

Each piece represents a single angle and can be combined, compared, and rotated to understand relationships between them. By turning angles into physical objects, this model helps bridge the gap between intuition and formal geometry.

Suitable for classrooms, workshops, homeschooling, or just experimenting with geometry.

Features

• Full 0–360° angle coverage
• Readable angle labels
• Consistent circular geometry (same system as Fractions made fun)
• Designed for intuitive use and repeated handling
• No supports needed

Customizable (OpenSCAD / MakerWorld Customize)

You can generate any angle you need:

• angle (0–360°)
• plate diameter
• thickness
• text size and placement
• optional center hole
• option to generate text separately for multicolor printing (export 2 stl files and then loadem as a single item into BambuStudio)
• if you don’t generate the text STL, the labels will be engraved directly into the plate; in that case, simply rotate the plate 180° so the engraved side becomes the top surface

Included

• Main kit (3MF) with a practical set of angles, shapes and bodies
• Parametric generator (create any angle on demand)
• Set of 15 to 360 degree angles in steps of 15 degrees
• Set of 15 to 360 degree angles with center hols in steps of 15 degrees

Ideas for use

• Compare acute, right, obtuse, and reflex angles
• Combine angles to reach 180° or 360°
• Explore symmetry and rotations
• Compare with fractions
• Hands-on geometry challenges

Notes

• Works great alongside the 
  • Fractions Made Fun set (where you can also find various types of containers that will fit these angles)
  • Modular Polygon Prisms – STEM Building Kit
