Tooth Brush Holder for Oral-B

This is a tooth brush holder fitting for 4 Oral-B tooth brushes and charging station Type 3757 (this type is included with a Professional Care tooth brush).
If you push down the holder onto the charging station the holder snaps into place.
The tooth brushes are hold in place, so they cannot touch each other.

I also designed a version for the old charging station Type 4729:
