Hello, I made a vial holder for my kitchen. Printed on the A1 with black Bambulab PLA Basic.
You will need to print the holder twice.

It is made to work with the Ikea Hultarp rails https://www.ikea.com/gb/en/cat/hultarp-series-53213/
My rail is mounted at 48 centimeters from the countertop to the center of the rail. 
It fits 12 vials with height of 20 centimeters and a diameter of 3. 

For the assembly All upper vial holders are with the PEI textured sides going up and the bottoms are with the texture facing down.
