About this 3D model

I made this design for the birthday of a very good friend. Most of the Dolce Gusto pad holders I found, are using a steal bar in the center. I made my design fully printable. And designed in a way you can make it grow, just by adding Pad Layers I printed it on a Prusa MK3, but I am planning to build one on my Nex X1. The print on the picture I made in Dark Blue PLA Filament. With a 0.4 nozzle. Settings Infil 15% 2 wall loops and 0.2 layer hight.
