A thin simple bookmark in 3 varieties:
Designed with a .2mm layer height in mind.
For multicolor I don't have a multi-color printer, but with a little effort you can achieve the same result by doing some minimal color changes. I followed the guide from this pi case, with one important addition… In Printer Settings, for each Extruder, set Retraction Length when tool is disabled to 0. Otherwise you get a big blob when the new color starts.
Design notes:
I found that by making 1 layer of the white go all the way through even the black parts, it adds strength to not snap off between colors.
These are a bit large. You might decrease the size by 80% or more.
