3D model description

The idea is the pencil sharpener.

For operational reasons, the project evolved into a pencil with a scroll wheel.

Simply because of the effort required to hold the pencil without recoil.

With a wheel, you can press the mechanism and turn at the same time.

This prevents the pencil sharpener from falling out when the pencil is pressed down to cut it.

This mechanism requires a simple pencil sharpener which is placed in a receptacle (the opening on the blade side).

The one used for mounting measures 16x11x26 mm (0.62x0.43x1.02 inches).

spacing:

-gear and body 0.2 mm on the diameter and 0.1 mm in the supports.

-pinion and pinion support 0.1 mm on the axle.

-rails have 0.05 mm with body and sprocket support.

The BOM and assembly steps are detailed on the images.

Model for 8 mm diameter pencils.
