3D Printed Bite Switch.

This project shows how to build a low-cost, customizable assistive bite switch using basic materials like a 3D-printed housing, a push button, soldered wires, and heat shrink tubing. The switch is designed for individuals with limited hand mobility, allowing them to control devices (like an adaptive controller or communication aid) using bite pressure.

How it works:

When the user bites down on the mouthpiece, the internal button is pressed, completing an electrical circuit. This sends a signal to a connected device—just like pressing a regular button.

Why This Matters

Assistive switches can be expensive, but this DIY version is:

1. Affordable
2. Customizable for comfort and sensitivity
3. Easy to repair or modify

Safety Notes

1. Ensure all edges are smooth and mouth-safe
2. Use non-toxic, food-safe materials where possible
3. Keep electronics fully insulated from moisture
4. Supervise use if needed

1. 3D-printed bite switch casing (custom design, STL attached)
2. Momentary push button (normally open)
3. Wires (thin, flexible)
4. Heat shrink tubing
5. Solder iron + solder
6. 3.5mm jack (optional, for compatibility with devices like adaptive controllers)
7. Soft padding or silicone (for comfort and safety, heat shrink works too)
8. Hot glue (for extra insulation for the wires)

Print!

Solder two wires to the button terminals. These act as your signal output.

Use heat-shrink tubing over solder joints to prevent shorts and improve durability.

Place the button inside the 3D-printed case so it activates when bitten. Route wires through the casing. Add padding or a soft layer to make it comfortable and safe for repeated use.

As it is only one button, suggested games are ones such as geometry dash, dinosaur game etc.
