This case is composed 6 pieces of clear acrylic sheets, and can hold your Witty Pi (or Witty Pi 2), Raspberry Pi and 7-Port USB Hub (BIG7) together. The acrylic sheets are 3mm thick and the case can protect your Witty Pi + Raspberry Pi + 7-port USB hub very well.
The top cover can be opened so you can connect/remove cables to/from the CSI and DSI connectors. There is also a window for GPIO header, so you can still access all GPIO pins.
Remarks: it doesn’t fit the newly released Witty Pi 3.
