Printed out the iPad Mini 4 and Nexus 7 2013 and the fit around the tablets was great.
Minor issue with the iPad Mini 4. I have to relocate the bottom bolts because it's interfering with the A/C vents.
But, here are some pics for the Nexus 7 2013
Might change the Window opening on the Nexus 7 since there are no hardware buttons, like on the iPad Mini 4 or the Galaxy Tab S2
