3D Printed Case for PD140W Fast Charging Module (DC 5.5x2.1mm)

Case for PD140W Fast Charging Module Enclosure for DC 5.5x2.1mm Input Version This is a custom-designed, two-part protective case for the high-power PD140W Fast Charging Module commonly found on Temu and AliExpress. It is specifically engineered to house the version featuring a DC 5.5x2.1mm input jack, providing a secure and professional enclosure for your DIY power setup. 🛠 Assembly & Hardware The case features a snap-fit design that locks the board inside, making screws optional but recommended for extra security. Screws: Recommended hardware includes 2mm self-tapping screws or standard M2 screws (15–20mm length). Tip: Depending on your print tolerances, you may want to use a small drill bit to clear the fixing holes for a perfect fit. Tool-less Alternative: If you don't have screws, the holes are sized to accept a short piece of 1.75mm 3D printing filament as a pin to secure the board and case together. 🖨 Printing Tips Since this 140W module can generate significant heat during sustained power delivery, material choice is important. Material: PETG, ABS, or ASA are recommended for better heat resistance. Standard PLA may soften under high loads. Orientation: Print the flat faces of both parts against the build plate for the best surface finish and to eliminate the need for supports. Infill: 20% or higher for structural rigidity, especially around the screw holes. Tested Settings: A successful print was achieved using Verbatim ABS-55026 at 0.16mm resolution . 📂 Design Files The enclosure consists of two distinct parts, available via Tinkercad : pd140wcase1b : The base/back section. pd140wcase2f : The front/top cover. 🛒 Hardware Sources If you haven't purchased the charging module yet, it can be found at the following retailers: AliExpress - PD140W Module Temu - PD140W Module
