Adaptor for Backpack USB cable to USB-C

I just got a new backpack with a cool USB port on the side which connects to a powerbank on the inside, but I wanted to replace it with USB type C, since I could charge my phone with it and charge the powerbank the other way. The Type A cable had a special shape to fit into the backpack so I printed an adaptor for it.

The USB-C extension I got is from UGREEN, if you use another one you might have to adjust the STL.
