Update: Hi all, based on some comments I hadn't seen before now, I have changed the license to be the same as that set by the original creator. I had assumed that uploading this as a remix would inherit the license level of the original and I didn't think to look. Please note that the license level is now set to "Non-commercial" please do your due diligence and review the terms of that license when considering what you want to use this model for.

This is the Batman cat mask by Myktattoo, just with the loose geometry removed. Opened the model in blender, found a few vertices not connected to anything but enough to upset the slicer and removed them.

All credit for this original work to Myktattoo. Happy Printing.
