Wii ModCase

Wii ModCase

The Wii ModCase is a more modern looking, mod-friendly, 3D-printable replacement case for the Nintendo Wii. It was designed and tested specifically for the Wii RVL-001 (2006–2010) model, so compatibility with other Wii revisions is not guaranteed.

The main idea behind the Wii ModCase is to remove the original mechanical disc drive while keeping the original Disc Drive PCB. The PCB is kept because some Wii software can check for the presence of a disc drive. This makes the ModCase especially useful for Wiis with mechanically faulty disc drives, while also creating more space inside the case for other modifications.

The case was designed to be easy to modify and adapt. It is made from multiple smaller parts rather than one or two large pieces, making individual parts easier to modify or replace. The design can also be adapted for modifications such as additional storage, USB Type-C, HDMI, or other custom electronics. The included STEP and Fusion 360 files make these modifications much easier to work with.

The ModCase uses the original Wii screws and required original components, so no additional mounting hardware is needed. The project includes fully prepared, print-ready STL files as well as the complete CAD files and a 19-page assembly guide. The Wii must be homebrewed before being disassembled, making this project best suited for makers and Wii modders who want to build and customize their own console.

The goal of the Wii ModCase is to provide a practical starting point for modification rather than a fixed final design. Once the basic case is built, what you do with the available space is up to you.

Before You Start

Before starting the physical modification, the Wii needs to be prepared in software and then completely disassembled. Complete the software modification before taking the Wii apart, and make sure the console is working correctly before continuing.

For the software preparation, follow the video below. It covers the complete software modification process needed to prepare the Wii for this project:

After completing the software modification, completely disassemble the Wii using the teardown video below:

When disassembling the Wii, remove every screw from the console, including all screws from the disc drive. Keep the original screws, as they are reused during the ModCase assembly. Also keep all of the original components listed in the Preparation section of the Assembly Guide.

Once the Wii has been completely disassembled and the required original components have been prepared, you can continue with the Wii ModCase Assembly Guide.

Printing

Use the Print Ready STL files for printing. These files are already oriented and prepared with the required custom brims, so no additional print preparation is needed.

Recommended settings:

• Material: PLA

• Nozzle: 0.4 mm

• Layer height: 0.16 mm

The 0.4 mm nozzle and 0.16 mm layer height are required for the provided print-ready files. Other settings can be adjusted to suit your printer and filament.

Files

The project files are organized into three main folders:

• Print Ready STL — Contains all individual parts prepared for printing. These are the files you should use if you simply want to print the ModCase.

• CAD Files — Contains the original .f3d, .step, and complete .stl files for viewing, modifying, or using the complete assembly in other software.

• Wii ModCase Assembly Guide — The complete 19-page PDF with everything needed to assemble the ModCase.

Have fun building and modifying it!

I've put a lot of time and effort into designing, testing, and documenting this project, so I hope you enjoy the Wii ModCase!
