When designing the Skara cup shelf , I already had something more 3 dimensional in mind. So here is the outcome, a modern looking cup shelf.

Size & Scaling: One cube is 155 x 155 x 125 mm. Overall size in the showed configuration is 425 x 425 x 125 mm. Scaling can be possible

Print settings: see last picture for print orientation 0.2mm layer height 2 walls 20% infill use a brim if you have adhesion problems
