Ex-esports commentator builds custom 3D mouse shells without AI
For enthusiasts who live at the intersection of gaming, engineering, and 3D printing, the quest for the perfect peripheral is often more complex than the hardware itself. It requires not just a desire for a unique shape, but the technical skill to design it, or the expensive luxury of buying multiple custom mice. Enter Bastian Recha, a German commentator and tech reviewer who is redefining this landscape with his innovative project, Mausstudio.
After a period of focusing on his craft, Recha recently unveiled a demo of Mausstudio, a tool that allows anyone to import an existing mouse PCB design as an STL file and start designing their own custom mouse shell. This isn’t just a digital experiment; it’s a practical shortcut for anyone wanting a mouse that perfectly matches their grip and aesthetic.
How does the magic happen? Mausstudio operates purely on the power of mathematics and algorithms, running entirely locally on the user’s machine. There is no reliance on generative AI to create the geometry, ensuring that the resulting designs are rooted in precision and user control.
The software works by analyzing the imported PCB file, automatically detecting crucial physical locations: the placement of mouse button switches, the sensor, the scroll wheel, and the screw holes. Based on these detected coordinates, Mausstudio then intelligently generates a shell that fits snugly around these functional components, adding the necessary stems, cutouts, and button placement required for a functional mouse.
But the true genius of Mausstudio lies in its customization capabilities. Users aren’t locked into a single design. They can freely adjust the width, length, height, and even the location of the ergonomic hump. Furthermore, the tool allows for advanced tweaks, including weight-reducing cutouts for the upper and lower shell, or even options for a fully enclosed design. Some of the most striking features address common frustrations in custom builds, such as the ability to customize the location and size of a dedicated battery shelf—a feature often overlooked in custom 3D-printed mice where battery placement is frequently an afterthought.
Mausstudio is designed to empower users who want to experiment affordably with various mouse shapes without needing advanced CAD skills or the frustration of hunting for existing custom shell designs. It transforms the daunting task of physical design into an accessible, mathematical exercise.
Since the initial demonstration, Recha has continuously refined the tool, adding features like editable component assignments, enhanced side button control, and cleaner geometry. While the project remains a work in progress—with no official release date or pricing yet announced—it is rapidly evolving. Future potential includes tackling more complex designs, such as split PCBs, positioning Mausstudio as a powerful tool for the next generation of custom hardware creation.
