Summary
The rubber boot near the brush head protects internal components but can tear over time from repeated head changes. In this case, water entered through the damaged boot, corroding the internal vibration weight and eventually stopping the toothbrush from working. This small replacement flange is designed to seal that area, replacing the torn boot and helping prevent future water damage.

Installation
I applied a small amount of food-grade NSF/FDA RTV silicone sealant between the 3D-printed flange and the toothbrush body to ensure a watertight seal and protect the internal components. After letting it cure for 24 hours, the repair was solid. It’s not the prettiest fix—but it's cost-effective and definitely better than buying a new toothbrush.
