Use your empty spools to store your acrylic craft paint bottles - it spins like a turntable, and stacks. I used creality spools for this but the spindle should fit in other spools as well. The drill guide has 35 mm holes which should fit the 2 ounce bottles perfectly, though I did have to widen the holes a bit for the old “Creamcoat by Delta” bottles which are just a hair wider.  Both models print without supports.
