Power bank hexagon case

thingiverse

In the files are multiple versions of the model, each allowing you to customize your power bank according to your needs. The central part comes in two variations: one with a circuit designed specifically for power banks and accompanied by a photo, while the other version is middle-clear without holes for USB ports, giving you the flexibility to create it using an alternative method. You also need to make a hole to accommodate a button, as shown in the picture. Mounting a 3D-printed button can be somewhat challenging because you have to attach the button to a piece of wire so that it can click freely. To overcome this challenge, I modified the PCB by unsoldering the button and replacing it with new wires inserted into a gap. For the LED hole, I drilled after printing and disconnected the LED from the board before reconnecting it with a wire. This case is designed to hold nine 18650 batteries but fits very snugly; you can use a silver strip or very thin wires to connect the batteries. Once everything is assembled, simply close up the case by gluing the front plate in place or mounting it using magnets or screws – I was too lazy to do otherwise and just glued it up.
