Split Cups for Acrylic Paint Pouring

I have been wanting to try split cup acrylic paint pouring for a while, but I couldn't find an STL online that suited my needs. Of course, I then created my own. I started out making a four compartment split cup for my particular need, but realized that it would be easy to make three and two compartment versions of the same basic cup. I included all three here. Hopefully someone will also be able to make use of them.
