eToothbrush Toothpaste drip off ring for Braun Oral B

I was wondering why the handpiece of electric toothbrush Braun Oral B series always gets dirty from my toothbrush foam. It runs down the shaft of the brush and then onto the hand piece and possibly onto the hand.
With this simple thing the fluid flows onto the peaks and drips off.
Easily flip on brush-replacement and paint them if you have multiple users in your home.
I printed them with my anycubic photon and wanhao resin.
If you like it or have suggestions about improvements please let me
