Use large metal clip.

3. Electric toothbrush holder

Most holders for toothbrushes are not large enough for electric toothbrushes. Ultimately, such toothbrushes fall out of the holder. Use large metal clip. Fasten it on one of your cabinets (best from the side where the toothbrush will not interfere). Insert the toothbrush into the clip and rejoice at how masterfully you organized everything.
