About this 3D model
I used to use empty creamer cups to mix paints, but I use those faster than we can drink coffee, so... here is my quick and easy solution. Depending on your settings, you can print half a dozen at a time in 20 to 30 minutes or so. The dimensions of the cup as posted are 10mm at the base, 15mm tall, and 15mm at the rim, with a 1.2mm wall. I included a scale model of a typical 2 oz. Plaid Apple Barrel / Folk Art acrylic paint bottle for size comparison... I was fresh out of bananas :)
