Crucial Note!!! Print using TPU filament!!! Please review carefully before printing to avoid wasting materials!!! This model is designed for the Xiaomi Inflatable Power Bank 2 PRO. Due to the protruding display screen, buttons, and rear light of the Xiaomi Inflatable Power Bank 2 PRO, only a flexible material can be used for printing to ensure a proper fit. Absolutely do not use PLA or PETG; they will not fit! The model in the configuration uses a 0.2mm layer height, 2 wall layers, 15% infill, tree supports, and TPU filament, with ventilation holes on the bottom and sides. There is a slight difference between the model in the configuration and the image: the image shows 5mm side ventilation holes, but the configured model has been improved with 6mm side ventilation holes and the removal of excess holes on the sides.
