Mobile charger from DeWALT li-ion battery

I used the QC 3.0 PLV quick charge board available on eBay at https://www.ebay.com/itm//153687027873 for my project. The dimensions of the board are 17 * 39 * 10. I placed it inside a case with internal volume approximately 17 * 48 * 14, and I believe there is sufficient space to accommodate similar PCBs. I tested the setup on a 10.8V battery, but since all DeWALT lithium-ion batteries have the same connector, it should fit other models as well. I added source files created using Fusion 360's free version to the project, including an accumulator and drill seat with tolerances of 0.3 mm in critical areas. You can use these files as cutting tools for your projects. The files are available in STEP format. For optimal printing results, I optimized the model for upright orientation, as shown in the attached picture. Recommended print settings include a nozzle size of 0.4 and 2-3 perimeters with optional filling. First-layer speed is set to 30 mm/s, with an optional skirt to clean the nozzle. External walls are printed at 60 mm/s with a layer height of 0.4mm, while internal walls, covers, and filling are printed at 80 mm/s with a layer height of 0.6mm. To create the contacts, I used a piece of tin, and it's recommended to solder the wires before inserting them into the case for best results.
