I don't sell any masks, I print them out and build for myself. The first mask, the dog's 3D files, can be downloaded for free from here, www.thingiverse.com/thing:250454 The Furby head is a little different, that one will cost you for the 3D files. You must joint Austin Bradley's patreon site , www.patreon.com/AustinBradley and it also needs to be built by ether you or someone for you, none of these come as finished items.
You can find the 3D files for the dog head here "www.thingiverse.com/thing:250454", but you have to build it. The eyes came from here, but they are out of stock.
