Dropper paint bottle holder

This little shelf holds 20 17ml (25mm diameter) Vallejo-syle paint dropper bottles.

After I saw and printed BlackBearProject's remix of this to "skeletonize" it, https://www.thingiverse.com/thing:2502903, I realized how badly I'd aligned the shelves, especially the bottom one. So, the OCD in me caused me to redesign this from the bottom-up as "Vallejo Dropper Paint Bottle Holder MkII" with properly aligned shelves. I'm only including the 1-piece print design here, because now that I've figured out how to do it in one piece, I have no interest in printing it in pieces ever again. That being said, feel free to mod the design on TinkerCad: https://www.tinkercad.com/things/9Am4iIjC1Y0-vallejo-dropper-bottle-holder-mkii.

There's an improved shelf that keeps the bottles in position better.

I added a one-piece shelf where you can print it all at once. (It just now occurred to me that this was possible.)

There's an optional base that you can glue to the bottom if you want to use the holder freestanding. It adds a bit more stability to the bottle holder. (Originally, this was designed to be hung on the wall, like a spice rack.)
