This is a 3D-printed safety cover designed to fit over the metal toggle lever (drain valve stem) on a standard bathtub overflow plate. In many older or traditional tubs, this metal lever is a significant "poke hazard" for infants and toddlers during bath time.
This protector provides a blunted, faceted surface to soften accidental bumps while still allowing adults to easily grip and operate the drain mechanism.
Design Features
- Child Safety: Transforms a thin metal rod into a wide, textured knob to prevent scrapes and bruises.
- Ergonomic Grip: The octagonal, faceted design ensures you can still flip the drain lever even with soapy hands.
- Low Profile: Designed to stay securely on the stem without interfering with the overflow drainage.
- Easy Installation: Friction-fit design (depending on your specific printer tolerances) that slides directly onto the existing metal stem.
