3D Human Models

3D Human Models

SLIMDESIGN created the 3D Human Models to validate designs at an early stage of the development process. We make the tool available for other developers through the 3D Human Model website. Beside Solid Works, we also have the other main Cad software available...

Smart Doorbell

Smart Doorbell

The smart doorbell design enables users to connect their doorbell to their phone. This project is a good example of how we introduce a lean start-up approach in established companies.


Switch Pen

We developed a pen with a smooth and addictive magnetic clicking mechanism to enhance the writing experience.



When SLIMDESIGN was tasked to design a new pen, we set the challenge of reinventing the traditional pen mechanism.



We wanted the mechanism to be satisfying, playful, and semi-addictive. We began sketching slides, switches, and various other ideas to open the pen. From there, we 3d printed the most promising concepts and made small adjustments to optimize the mechanism.



In addition to the new satisfying mechanism, we invented a new pen grip that gives the user the option to choose if they want to use the pen grip. The classic hexagonal design gives the pen a timeless experience.

We placed the switch on the side of the pen and the grip on only three sides of the hexagonal body, giving the user an option to use the grip or not.

We prototyped a variety of mechanisms and tolerances before reaching a final design.

The mechanism uses magnets to achieve a satisfying “snap” when opening/closing the pen.
