Try this image. I may take those front tabs off, i don't think they need to be there. As another poster noted, the back edge at the ends also need trimming back a little as they curve inwards to help cradle the original Z10 shape. There is enough screen edge exposed on the bottom edge to enable swiping up.
I attached a USB flash drive to the cradle using a usb-otg cable, put my phone in the cradle and it was found ok. I also tried a couple of hard drives. As soon as I connect them, I get a hub notification stating USB device problem. I'm guessing it may be down to power requirements not being met through the phone. I enabled USB mass storage mode on the phone and connected my phone/cradle to my laptop, where it found the SD card on my phone.
To be honest, the USB and HDMI ports on the cradle are just pass through connectors, so whatever works on the phone, will work on the cradle.
