Mini vibrator massager based on an oscillating toothbrush.
You must cut the hairs of the brush as close as in the photo. Two types of fixing are available.
One with screws, the other simpler with a drawer.
Screw 2x10 and an 8x3x1 washer.
Use double-sided tape with a small thickness of foam to glue the two parts together (see photos).
The replacement brushes are the iO series with an elliptical shape approximately 14.75 x 13.86 mm.
To be produced with a resin printer for a smooth finish.
