About this 3D model
This is version 2 of my insert: As I painted I ended up with 3 palette's for different reasons. I decided to create the insert for my Army Painter Wet Palette. It enables you to still use the main palette for your acrylics. You can use the small mixing pits for your paints that is not suitable for the wet palette as it seeps through the layer into the hydro material. These are for speed paints, metallics, washes ETC and they will stay wet when you close the lid. I changed the drybrush palette area to be more usefull of me and the main acrylics area allows for better colour mixing.
