UPDATED SUPPORT MODEL - FIXED! Some part of the support was crashing through the base, if you have auto centre enabled in slice it will offset the bottom causing problems.

I took the model and cleaned it up in Zbrush, removed weird cavities and thickened the walls.
FIXED - For FDM Printers ( scale OK )
Supported - Support added for SLA / DLP Printers.( do not scale ), hollowed 2mm
