About the Project
A small and simple adapter to block the power connection of a USB port.
Whenever you need the USB data connection but must prevent the device from charging or drawing power, you can use a tool like this. This is especially useful for octoprint when connecting your raspi to your 3D printer.

You can use a tool like this whenever you want to make sure a USB port is used for charging only. This is especially useful when using public or otherwise untrusted USB devices to prevent BadUSB attacks.

Before you print
I designed this case specifically for my setup:
- Prusa Mini
- 0.4mm nozzle
- Prusament PETG
- 0.2mm SPEED
I print the data blocker case in blue and the power blocker case in orange.
