Anker 535 Dock

SummaryNot long ago, Anker upgraded its 10000mah power bank. Now the Anker 535 has an LCD, which allows me to see the remaining power at a glance. No more guessing by the number of indicators. Therefore, I bought three to ensure that at least one power bank is fully charged before going out. Because Anker 535 has curved edges, it cannot simply be stacked. I ran into a storage trouble. So I designed a simple storage dock that can put these three power banks together. I also have the idea of adding a charging port and turning it into a charging base. The design is not complicated, I built the hollow cube in TinkerCAD using Anker 535 dimensions and then combined it with a solid cube.
