A webapp called Iris Calculator was used to generate an aperture that can hold bottles with diameters ranging from 1.5’’ to 2.75’’. Originally, the aperture was 3D printed, but the calculator had adjusted my outer diameter dimensions to be about 6 inches, much larger than what was needed, based off of other parameters. A second aperture mechanism was made that was about 3.7 inches in diameter. I lasercut the DXF files from the webapp instead of 3D printing for a better finish (3D printed parts had coarse surfaces) and would be faster to manufacture.
