USB Data/Power Blocker Case

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.
