Paint palette with additional small containers

Some time ago, while painting figures, I was wondering how to minimize the final process of cleaning tools. Idea was born to create a paint palette with the possibility of replacing small paint containers (can be used multiple times for the same color). Advantages: -tool does not require washing, saving water and time. -ability to adjust color palette at any time -perfect solution for printing from the end of a spool 0.8-0.9g per piece
