I'm AhSerif, a Berlin-based 3D artist and motion designer, and the founder of ZEROtweak. My work is driven by a simple philosophy: bridging the gap between the speed of digital creation and the lasting presence of tangible, functional objects.

ZEROtweak is the result of merging the cutting-edge power of digital manufacturing (3D Printing) with a passion for precise, industrial design. We operate with zero tolerance for anything less than perfection in crafting smart, technology-driven solutions for everyday needs.

Starting with the Analog: The Seigaiha Collection 

We began this journey by designing accessories for the analog world, merging functional durability with a meditative design philosophy. Our initial products, the Seigaiha135 and Seigaiha120 film storage cases, are the physical proof of this mission.

The name "Seigaiha" refers to an ancient Japanese wave pattern, symbolizing peace, resilience, and continuous good fortune. By incorporating this philosophy into our products, we turn each case into more than just a protector; it is a quiet symbol of longevity and calmness for your timeless passion. These cases preserve the simplicity of the analog process using modern, sustainable technology.

Every item is carefully produced and hand-finished in our Berlin workshop. We are committed to sustainability, exclusively using eco-friendly materials such as biodegradable PLA. For us, design must be not only aesthetic but also functional, enduring, and responsible.

Every object we create at ZEROtweak is a deliberate, small adjustment—a 'tweak'—connecting the technology of the future with the soul of the past.
