Looking for components

Heyo!
I wanna try making an electric toothbrush, I am reusing a perfectly fine dc motor I harvested from a dead Oral-b toothbrush.
I want to make both the toothbrush pcb and a base for it
Settled on the MSPM0C1104 microcontroller, DRV8833RTYR motor controller, MPU-6050 for the IMU, and the CN3058E for charging.
You might notice that I'm not using any regulator for my components, this is beacuse I am using a LiFePO4​ battery (voltage goes up to 3v6).
The base station will most probably house an esp32 and will connect to the brush via audio jack.
The cases will be designed in 3D and printed on my own printer I have at home.
