Intersex Pride Progress Pride Flag Multicolor

I couldn't find anything like this so decided to try my hand at it in Tinkercad. Simple enough idea. The color changes ever 1mm (plus extra 1mm at base). I printed it all with the same nozzle, manually changing and purging in-between colors.

If rescaling smaller, I recommend only scaling in X and Y to keep 1mm layers

I bought a pack of 3D pen filament to get all the colors. If you decide to go this route, be warned that 3D pen filament is not often good quality filament. Even still, it printed fine as I used high quality filament for the first 1mm base to get good build plat adhesion.
Diameter is inconsistent, and I even measured as low as 1.67 on a section of my yellow spool.
Mine also showed up in a vented bag exposed to air. I left it in a container with desiccant beads for a week or so before using to be sure it wasn't wet.
