Ex-CS:GO Commentator Builds AI-Free Generator for 3D-Printed Mouse Shells

Mausstudio, a tool demonstrated on October 28 by former CS:GO commentator Bastian Recha, generates fully customizable 3D-printable gaming mouse shells from an imported PCB model — and it does so without any generative AI.

Recha, known online as "Unskilledcast," is a German tech reviewer and 3D printing enthusiast. He returned to X after six days of silence to post a demo video of the software he had been building, showing how users can shape a mouse around the electronics they already own.

How does the software actually work?

The process starts with an STL file of a mouse PCB. In his demo, Recha used scans of the Razer Viper V2 Pro and the Zaunkoenig M2K, two popular boards among mouse modders. The software then analyzes the file and automatically detects four key component locations:

• Mouse button switches
• The optical sensor
• The scroll wheel
• Screw holes

From those detected points, Mausstudio generates a shell that fits the board. It places stems that reach the switches, cuts an opening for the scroll wheel, adds buttons for the side switches, and leaves a base cutout so the sensor can track properly. The user never has to open a CAD program.

Recha stresses that the entire tool runs locally on the user's machine. No generative AI is involved. In his words, the software relies on "just math and algorithms."

What can users customize?

The demo showed adjustments to the width, length and height of the shell, including the position of the hump — the curve of the mouse that determines grip feel. Users can also add weight-reducing cutouts to the upper and lower shell, or choose a fully enclosed design without them.

One feature Recha highlights is the battery shelf. Users enter the dimensions of their battery, and the software builds a shelf of the right size in a position of their choosing. He argues this is where most custom 3D-printed mice fall short: battery placement is treated as an afterthought, typically solved with hot glue or double-sided tape. Mausstudio makes the battery a designed part of the shell rather than a loose component.

The takeaway: the tool turns shell design into a set of sliders and dimension inputs, with the geometry handled by the software.

Has a release date been set?

No. Recha has not announced when Mausstudio will be released, nor whether it will be free or paid. He has, however, posted an update on progress since the demo:

• Detected component assignments can now be edited
• Side button placement has more control options
• Shell designs can be saved and reused on other PCBs
• The generated geometry is cleaner

Split PCB designs, such as the one in the Logitech G Pro X Superlight, remain an open question. Support for that layout may arrive in future versions, though Recha has not confirmed it.

Why does this matter for gamers?

Good gaming mice are expensive, and shape is the hardest thing to get right. Players who chase the perfect fit often buy many mice just to try different shapes, an approach that costs real money. A tool like Mausstudio could let a user keep their existing PCB — and its working switches and sensor — and experiment with shell shapes at the cost of printing material.

It also removes the CAD barrier. Until now, a custom shell meant either learning 3D modeling or hoping someone had already designed a shell for your exact PCB. Mausstudio covers the design step for you.

Whether the software delivers clean, printable results at release will decide its value. If it works as shown, the mouse shell becomes a cheap, repeatable experiment rather than a purchase decision.
