Introduction

I needed a wet palette, and I had some plastic Pringles lids lying around. So, in the spirit of upcycling, I designed a wet palette that incorporates them and does not use a lot of filament.

Recommended settings

• 100% infill (shouldn't really matter, but just in case)
• set all infill patters to concentric
• 0.2mm layer height
• I recommend at least 0.6 mm extrusion width

Assembly instructions

You will need

• 3D-printed parts
• two plastic Pringles lids
  • one to use for the bottom and one for cover, so if you don't need to cover the palette, you will only need one
• disposable kitchen cloth
  • this is for the wet "sponge" layer, so feel free to use whatever else you have at hand - in a pinch, even some paper towel should work
• piece of baking paper

Steps

1. Take the baking paper and cut out a circle roughly 78mm in diameter. This will be the surface of the palette, so it's a good idea to cut some more to keep as spares, as you will need to replace it after every couple uses.
    
2. Take the viscose cloth (or whatever you want to use as the "sponge" layer) and cut some circles about 72mm in diameter. The wet layer has to have roughly the same height as the ring part, so cut as many pieces as needed to achieve that (I use two). The layer will likely become slightly thicker when wet, so try to account for that.
    
3. Place the circles of viscose cloth in a lid.
    
4. Insert the ring part, flat side up, into the lid with the cloth in it. You will need to press it in firmly.
    
5. Pour some water into the lid to soak the wet layer. It has to be soaked but not submerged in water, so pour out the excess (if the water pools up at the side when you tilt it, it might be too much).
    
6. Put the baking paper circle under water for a couple minutes to saturate it. It expands a little when damp, so if you don't do it before placing it on the palette, the surface will wrinkle.
    
7. Place the circle of baking paper on top of the wet layer. Smooth it out and push out any air bubbles if needed.
    
8. Insert the grid part, with the grid facing the bottom and pressing against the baking paper - it should snap in place.

Done!

Tips

When painting with easily flowing low viscosity paints (contrast paints, speedpaints, etc.), be careful not to put paint near the grid lines or the edge of the palette - if it touches the edge, it will get sucked under it by capillary action (found out the hard way).
