Petty Knife Holder

The surface of the grip has bumps to make it less slippery. Thanks to the parametric design, you can choose the cross-section shape from a circle, equilateral triangle, or square, and you can create a hole to match the writing instrument you use.

Adjust the size of the petty knife handle and the thickness of the palm part to form an appropriate cuff. The inside of the cuff may feel unpleasant to the touch due to filament stringing, so pay attention to the slicing settings.
