Grab existing unfinished CAD and finish it. Not much left to do.

The task is to grab an existing almost finished CAD model and finish it.

The CAD model itself is an enclosure for a payment terminal, accommodating screen, main board, some additional small boards and a keypad. You can see it, photo and video, at xbterminal.com.

Only minimal changes left to do, but I'm not sure how to explain it, need to show on the actual model on skype.

I'm unable to attach CAD files as it's over the attachment size limit. Will share in dropbox.
