Rotary pencil shaperner 3D print model

Idea is that of the pencil sharpener.

For operational reasons, the project has evolved into a pencil with a scroll wheel.
Simply because of the effort required to maintain the pencil without the set back.

With a wheel, you can press the mechanism and turn at the same time.
This prevents the pencil sharpener from falling back when the pencil is pressed to be cut.

This mechanism requires a simple pencil sharpener that is positioned in a receptacle (the blade side opening).
The one used for mounting measures 16x11x26 mm (0.62x0.43x1.02 inches).

Model for pencils 8 mm in diameter.
