Backpack straps ports

thingiverse

I wanted to create a power port in my backpack straps, allowing me to charge my phone while moving without relying on a power bank or dealing with cables. To design the part, I thought it would be convenient to also include a 3.5mm jack for audio if I ever placed my phone in the back and still listened to music. A single ring jack was used initially, but switching to a three-ring one enables mic usage on some headsets. I produced four distinct parts: 1. A USB-only design 2. A 3.5mm Jack-only model 3. A combination of 3.5mm Jack and USB 4. Dual USB ports A stranded Cat 5e cable was used for connections. To secure the backpack's fabric, I recommend using eyelets and/or carefully burning around any holes made to prevent fabric breakdown and maintain the backpack's strength. Enjoy!
