wall mount for 100 ml spice bottle / wide neck reagent bottle

An easy wall mount for 100 ml spice bottle (old wide neck reagent bottle).
The bottles are about 52.5 mm in diameter and are perfect to store differenet spices. To save some space in my kitchen I designed this wall mount. I glued multiple of these together with double sided tape and taped them to the cabinet door. Therefore only three screws were nessecary to mount 10 of them to the door.
