## Function

The Buttons are small caps that sit over the tactile switches beneath the display. This component:

* Provides a comfortable press surface for the three under-screen buttons
* Transfers actuation force to the underlying tactile switches
* Features optional translucent sections for LED status indicators
* Three buttons required per remote

## Print Settings

| Setting           | Value           |
| ----------------- | --------------- |
| Layer Height      | 0.12mm          |
| Walls             | 4               |
| Infill Type       | Gyroid          |
| Infill Percentage | 30%             |
| Supports          | Minimal or none |

<Tip>
  These are small parts. Use a brim for bed adhesion if needed, and print multiple at once for efficiency.
</Tip>

## Multi-Color Printing (Optional)

The buttons include a separate body for the LED indicator area:

| Area             | Purpose                 | Recommended Material    |
| ---------------- | ----------------------- | ----------------------- |
| Indicator window | Shows button status LED | Transparent/translucent |
| Button face      | Press surface           | Any opaque color        |

<Info>
  Multi-color printing is optional. Single-color buttons work perfectly—you just won't see the status LEDs through the button caps.
</Info>

## Installation

<Steps>
  <Step title="Print three buttons">
    Print all three button caps using the settings above.

    <Check>
      Buttons are free of stringing and have clean surfaces.
    </Check>
  </Step>

  <Step title="Test fit">
    Place each button into its housing slot in the top enclosure. They should move freely up and down.

    <Warning>
      If buttons bind or stick, lightly sand the sides. Do not force them into place.
    </Warning>
  </Step>

  <Step title="Verify actuation">
    With the PCB installed, press each button to confirm it properly actuates the underlying switch.

    <Check>
      Each button clicks cleanly and springs back when released.
    </Check>
  </Step>
</Steps>
