Mausstudio is a work-in-progress project designed to generate a custom mouse shell around an imported 3D model of the mouse’s PCB, or circuit board. Developer Bastian Recha says the tool generates geometry locally with mathematics and algorithms. A demonstration report describes controls for changing the shell’s shape and internal layout.

From a PCB model to a custom shell

Recha’s post, dated October 27, 2026, describes importing a PCB as an STL file, a common format for 3D models. The planned workflow starts with that board model, rather than scanning the outside of a complete mouse.

Tom’s Hardware reported that the demo identified locations for switches, the sensor, scroll wheel and screw holes, then generated corresponding shell features such as switch stems and openings. It also showed adjustments for shell width, length, height and hump position. Users could choose between weight-reducing cutouts and a closed shell, and set the size and position of a battery shelf using entered battery dimensions.

The report also described later changes to the project: editing detected component assignments, adding more control over side buttons, reusing saved designs with other PCBs, and cleaner geometry.

The PCB STL may take work to obtain

The shell-design step depends on having a suitable PCB model. Modders Inc reported on October 31, 2026, that Mausstudio was not available to download at that time. The outlet also reported that manufacturers often do not publish PCB models, so users may need to measure or scan a board and create an STL themselves.

The demonstration included PCB models for the Razer Viper V2 Pro and Zaunkoenig M2K, according to Tom’s Hardware. Those named examples give a sense of the boards shown in the demo; they do not establish support for other mouse designs.

What Recha’s no-AI statement covers

Recha says Mausstudio uses mathematics and algorithms, rather than generative AI, to create shell geometry. That statement is about geometry generation. It does not describe how the application’s code was written.

The project remains a work in progress, as Recha described it in his October 27 post.
