E File repair

I designed replacement parts for a handheld wireless e-file to improve its durability, especially when used in wet environments. The original device had ball bearings that rusted easily, so I created an alternative solution without using ball bearings.Components: Motor Adapter: A custom adapter to securely hold the tool and connect it to the motor. PTFE Bearing Cover: A bearing cover made from PTFE (Polytetrafluoroethylene) to reduce friction and prevent rust. Internal Bearing Cover: Placed inside the PTFE bearing cover to further reduce friction.Assembly Instructions:Remove the Original Ball Bearings: Disassemble the e-file and remove the rusted ball bearings.Attach the Motor Adapter: Secure the custom adapter to the motor to hold the tool firmly.Install the PTFE Bearing Cover: CNC machine the PTFE bearing cover to the correct dimensions. Insert the internal bearing cover into the PTFE bearing cover.Reassemble the E-File: Reassemble the e-file, ensuring all components are aligned and secure.Notes: The PTFE bearing cover is CNC machined for precision. A 3D-printed version may work, but it has not been tested. This modification ensures the e-file operates smoothly without the need for traditional ball bearings.This solution enhances the durability and performance of your handheld wireless e-file, especially for tasks involving water.
