Thickening

Morning, everybody,
When I thicken the attachment I get an error (in solidworks 2015), the other day with a similar design I didn't get an error.
I'd appreciate it if you'd give it a thickness of 0.8 mm out and send it to me.
Greetings and thanks in advance.

Thank you very much for the clarification.
With which program you have solved it and how you have done it.
Could you send me an explanatory video?
Greetings and thanks.

You have some small faces (<.0.005 mm) causing the problem. I would delete and rebuild these sections. The model should thicken after they're corrected.
