Wire Bathroom Stand Accessories

Specific to the stand (Walmart-Mainstays if I recall?) shown in the images, or wire shelving with 30mm on center wire spacing, these snap on accessories provide a toothbrush holder and a simple tablet/phone stand.
They snap over the shelf wires and stay firmly in place.
It is easiest to snap them on in the center of the shelf wire away from the perpendicular support rods where there is some extra give, then slide easily to either side to desired position.

I believe this is the unit I had purchased:
