#Update 1: The box now has a small locking mechanism. Bed adhesion was improved.
These sets of set squares allow one to quickly check if the students made the angle correctly. Very useful when you have a big class to check.
They were made using the property that any point in a semicircle makes a 90° triangle with the diameter line. So they fit in a circular box.
Printing
Print the set squares with a small layer height.
Box:
Material: PLA
Layer height: 0.2 mm
Supports: Not required
When loading the box_top part load it as a single object with multiple parts. This will make removing the bed adhesives easier.
Setsquares:
Material: PLA
Layer height: 0.15 mm or lower
Supports: Not required
Assembly:
Use a M4 screw and bolt for the box hinge.
When putting the lock piece the square connector goes to the bottom so that it stays stuck. The triangular side faces the top part of the box.
