Khắc Phục Cổng USB A Máy Prusa Mini

This 3D model was specifically designed to facilitate firmware updates on a Mini+ with a damaged USB-A port. The damage appears to have been caused by the forceful removal of a previously connected device, which resulted in the internal tang of the port being dislodged.

If you're facing a similar issue, first ensure that the pins within your USB port are realigned to their original positions. You can use the interior of a USB stick as a reference to achieve the correct spacing between the pins.

After aligning the pins, insert this custom-designed tang into the port as illustrated in the accompanying images, leading with the shorter edge. The pins' bent sections should settle into the model's valley once the tang is in place. Then, gently guide your USB drive over the tang and into the port.

Please note that while my initial attempt with one USB drive was unsuccessful, a second drive functioned flawlessly, enabling an update from firmware version 4.4.0 to 5.1.0.

Below is the link to the drawing used for designing this tang.
