Step-by-Step Instructions
Step 1: Design and Print the Power Bank Case
Start by designing your power bank case using CAD software or downloading a pre-made design. Ensure the case has compartments for the batteries and space for the BMS and USB modules. Print the case using a 3D printer.
Pro Tip: Use PLA or ABS filament for durability.
