## Function

The Bottom Housing is the lower shell of the RADR wireless remote. This component:

* Forms the battery compartment for the rechargeable battery
* Provides the rear ergonomic surface for comfortable grip
* Contains mounting bosses for PCB attachment
* Features the USB-C charging port access
* Mates with the Top Housing to complete the enclosure

## Assembly Notes

<Steps>
  <Step title="Check fit">
    Test fit the PCB and battery before final assembly. Verify the USB-C port aligns with the housing opening.

    <Check>
      The PCB sits flat on the mounting bosses with no interference.
    </Check>
  </Step>

  <Step title="Verify clearances">
    Ensure the battery fits with adequate clearance. Some printer tolerances may require light sanding.

    <Warning>
      Do not force components. If fit is too tight, sand lightly rather than applying excessive force.
    </Warning>
  </Step>
