About this 3D model
Mount for a USB Hub you can attach to the RigidBot frame. I use it to power USB fans and lights. Uses a [usb hub with switched ports](http://www.dx.com/p/199116?Utm_rid=80235630&Utm_source=affiliate)* and 4 cylindrical magnets (6mm diameter x 4mm height). The magnets are optional, and work as a tool holder. **affiliate link*
