Oral B IO Toothbrush Charger and Head Holder

Feel free to adjust the negative volumes to make the ventilation shafts bigger or smaller to fit your needs.

The second version has a bigger ventilation pipe in the bottom. Also i Added a negative volume to remove the backrest. Feel free to disable it, it you want the backrest.

I added 2 vertical and one horizontal shaft for ventilation. So the brushes dry on the inside. I find this quite important to avoid mold in inside the brushes.
