This is a very printable mask worn by some of the splicers in the hit video game Bioshock. A great deal of care has been taken to ensure that this is as accurate as possible to the game, using extracted models from every Bioshock game (Bioshock/Bioshock 2/Burial at Sea) as reference when digitally sculpting to make sure that this is the perfect Bioshock mask.
It has been scaled to print, so that once printed it will fit the average person's head, with a bit of room to put some padding on the back to ensure it's comfortable to wear, or simply hang on a wall (it makes a great display piece).
Both the masks in the picture were printed using 0.2mm layer thickness, with a 0.4mm nozzle with a 1.2mm wall thickness and 10% infill. For support structures I had support only for parts touching the ground. The model has been angled so that if printed this way, it will make a stable model without too much of the face detail being given unnecessary support.
The model pictured on the left is as it has come out of the printer, with the support removed, the one on the right has since been sanded and painted for use at a costume party.
EDIT: As requested, I've sliced up the bunny mask, so now it can be printed in parts on any printer the size of a Flashforge or larger.
