Video on adjusting the angle of the palette extension if it seems to be angled to much. (This is a rough video but will give a good overview of a solution and why it was designed the way it was. And while the box in the video is the Cigar Box™, this applies to all Palette Extension Kits and the Guerrilla Painter® boxes that can have extension kits installed in them.)
