USB Back-Power Blocker
thingiverse
Inspired by https://www.tindie.com/products/brianlough/power-blough-r/. Even more directly inspired by https://www.thingiverse.com/thing:3044586. I designed my version from scratch, making "remix" not a great fit, but it's definitely a direct successor. My version is much sturdier. The pins connect only in the middle, allowing both sides to be enclosed securely. PS: A bit of kapton tape probably works just as well and is faster and easier. _Jul 10, 2019 update:_ Kapton/any other thin tape definitely works and is faster and easier. I've tried it out. It makes this 3D printed thing completely unnecessary. Just use some tape.
