I stumbled upon a 3d model made by stigberg, printed it and showed to my colleague, a math teacher. She really liked them and wants to use them in classroom, but she pointed out that reflex angles are missing. In order to complete the set I added 240° and 270° angles.
That way you have all types of angles available:
- Acute angle (<90°) - 30°, 45° and 60° angles
- Obtuse angle (>90° and <180°) - 120° angle
- Right angle (90°)
- Straight angle (180°)
- Reflex angle (>180° and <360°) - 240° and 270° angles
- Full rotation (360°) - you can assemble it with some of the angles above
All angles are 2 cm thick, but feel free to scale the Z axis to make them thinner and print faster.
