Mirror / See back or an isometric shape

[markw60549560]

Hi

Anyone know how I could create this effect? I want to see the back of a isometric sign / lettering. see pic.

I keep reflecting and rotating but no luck. Any ideas?

Thanks

Mark

Do you need it as an effect? 

Does this need to be precise?

Please give us some context of the task
