Raspberry Pi Pico 2 W Case with Wiring Grommets

This is a simple protective case for the Raspberry Pi Pico 2 W, designed for hobby electronics, maker projects, and 3D printer tuning setups.

The case includes a bottom enclosure, a top clip-on lid, internal screw posts for M2x4 screws, and two grommet holes sized for 4 mm ID / 6 mm OD grommets. The grommet openings are intended to provide basic strain relief for wiring.

This case was originally designed and used as part of a Klipper input shaping setup with an accelerometer on an Ender 3 V2.

Features

• Designed for Raspberry Pi Pico 2 W

• Top clip-on lid

• Bottom case with M2x4 screw posts

• Two grommet holes for 4 mm ID / 6 mm OD grommets

• Useful for wiring strain relief

• No supports required

• Includes individual STL files and 3MF files

• Includes a Cura project export showing print orientation and infill modifier

Suggested Print Settings

Material: PLA or PETG
Nozzle: 0.4 mm
Layer height: 0.24 mm
Walls: 3
Top/bottom layers: 4
Infill: 20% or higher
Supports: No
Brim: Optional
Orientation: Print flat side down

Clip Strength Note

Supports are not required.

For best durability, I highly suggest using 100% infill on the lid clips if your slicer allows local infill modifiers. This is not required, but it may improve clip strength and long-term durability.

A Cura project file is included with the print orientation and modifier setup.

Hardware / Parts

• Raspberry Pi Pico 2 W

• M2x4 screw

• Optional: 4 mm ID / 6 mm OD grommets

Known Limitations

This case is intended for light-duty indoor hobby and prototyping use. It is not waterproof, not dustproof, not impact-rated, and not intended for high-temperature, outdoor, industrial, or safety-critical environments.

Board tolerances, wire routing, screw fit, and grommet fit may vary slightly depending on your specific parts, printer calibration, and material.
