The assembly process is not difficult, but following the correct order makes it much easier and helps avoid mistakes.
I can add detailed step-by-step instruction to download if needed. just let me know.
The plug stays in place with the force of friction.
Ideally, print it with 100% infill. There is no need for using supports.
Despite the relatively low voltage, this project involves electrical connections, including Li-Ion batteries capable of storing large amounts of energy.
Depending on the materials used, print quality, electrical connections, and assembly method, there may be a risk of fire, short circuit, overheating, or electric shock.
Before starting any work, make sure that you have sufficient technical knowledge and experience in working with electrical systems and batteries. If required by local regulations, ensure that you hold the appropriate qualifications or permissions.
Always use proper insulation, adequate wire gauges, and suitable protective components (such as fuses or circuit protection) when integrating this adapter into a project.
