I wanted the rounded aesthetic of https://www.printables.com/model/294223-epson-115-ecotank-ink-holder but the 4 bottle holding of https://www.printables.com/model/284001-epson-502-ink-holder so I took those ideas and made this model in Fusion 360.
I used PLA on .30 Draft mode with 0 infill as it's mostly curves and it's doing great.
UPDATE: Added a “paw” like shape since I was playing around the layout.
UPDATE: 5/20/23: Added an 8 bottle holder as I got 2 Bk bottles
UPDATE: 5/26/23: And now I decided I wanted to hang 4 of them on the wall, so adding a wall mount version.
The author remixed this model.
