This is designed to fit in your car cupholder and hold the KBOX mini. It also works as a nice solid desktop stand.
There are 3 versions: a barebones one, a barebones one with an extra cutout for a bottle holder (up to 25mm diameter), and a solid one. Not surprisingly, the solid one uses the least amount of filament if you print it with 20% infill or less.
No need for support. Print with 15-20% infill for a solid but light part.
