Stackable Box

This is a remix of http://www.thingiverse.com/thing:234669 which is a remix of http://www.thingiverse.com/thing:177814.
I removed the 'Ears' as i have a heated print bed and the print sticks fine.
There are 2 files one is a single box the other has 2 on bed (fits a 200mmx200mm bed)

I have also included the original stackable box with no 'ears' the original has 5mm think walls where as the remix has 1mm thick walls
