ReMouse Dell MS116

🖱️ ReMouse MS116 – Repairable OEM USB Optical Mouse

ReMouse Project is a 3D-printable replacement shell designed to repair OEM USB optical mice instead of throwing them away.

In schools and shared environments, mouse buttons often fail while the internal electronics are still fully functional.
This project allows you to reuse the original PCB, USB cable, scroll wheel, and screws, replacing only the broken plastic shell.

The design is intentionally simple, robust, and efficient, focused on repairability, durability, and future adaptability.

Why ReMouse

Most OEM mice are discarded due to simple mechanical failures, usually broken click buttons, while the internal PCB still works perfectly.

ReMouse Project aims to:

• extend the lifespan of everyday electronic devices,
• reduce electronic waste,
• promote a repair-first mindset instead of replacement.

This project fits naturally into eco-responsible practices, educational workshops, repair cafés, fablabs, and schools.

The manufacturing of a standard office mouse represents around 3 kgCO₂e, according to estimates based on the ADEME carbon database. (source)

Beyond repair, ReMouse also gives a second life with a bit of personality.

• The shell color can be freely chosen, allowing you to add some visual “pep” to an otherwise generic OEM mouse.
• Ideal for color coding, classroom identification, or simply making repaired devices look fresh again.

The overall shape remains minimal and ergonomic, focusing on comfort and efficiency rather than unnecessary complexity.

STEP File Included (Design Modifications Allowed)

The STEP file is included to allow:

• design customization and modification,
• adaptation to other OEM mouse variants,
• educational or technical use (analysis, improvement, demonstrations).

 The STEP file is provided to encourage learning, experimentation, and improvement, especially for teachers, makers, and fablabs.

Dell MS116 PCB Compatibility

Assembly

Step 1 — Install the optical sensor lens Place the optical sensor lens into the designated slot in the mouse base. ⚠️ Important: the lens has an orientation. Make sure it is aligned with the optical sensor on the PCB.
Step 2 — Route the USB cable Insert the USB cable into the guide located at the front of the mouse base. Then route the cable between the scroll wheel supports, as shown in the image.
Step 3 — Install the cable clamp Insert the cable clamp from the top of the mouse base. Then slide it onto the cable guide located at the front of the base, as shown in the image.
Step 4 — Install the PCB and position the cable Remove the cable from between the scroll wheel supports. Install the PCB onto the four mounting posts (circled in green) provided for this purpose. Once the PCB is in place, insert the cable into the base guide along its entire length, as shown in the image (blue arrows).
Step 5 — Install the top cover Place the top cover of the mouse as indicated by the green arrow. Then push the shell in the direction indicated by the blue arrow until it snaps into place (click).
Step 6 — Secure the base Tighten the original MS116 mouse screw into the designated hole, as shown in the image.
Your ReMouse MS116 is now assembled and ready to use. Thanks to this 3D printable repair design, you can repair and extend the life of your Dell MS116 mouse instead of replacing it.
