Add a touch of nature to your furniture with these functional butterfly-themed drawer knobs and cabinet pulls. This set includes both a symmetric front-facing view and a graceful profile view, allowing for a dynamic and personalized look across your cabinetry. These models are optimized for easy printing, providing a practical and stylish hardware refresh for any room.

Designed for effortless assembly, these knobs feature a versatile mounting hole optimized for M3 screws. The material is specifically engineered to be resilient yet forgiving; as you drive the screw in, it will naturally carve its own precision threads into the plastic. This creates a custom, high-friction fit that ensures your hardware remains securely fastened and wobble-free, whether you use self-tapping or standard machine screws.

For imperial sizes, a #4 screw (specifically #4-40 machine screws or a standard #4 wood screw) should work well. 

In each case, the length of the screw depends upon the thickness of your drawer or cabinet front. But the mounting hole is about 13 mm, or about one half inch. 

Any rigid filament should work. The models can be scaled. But be aware that the size of the mounting screw may change, depending upon whether you make the knobs bigger or smaller.
