First off let me get this straight, The file its self is very good. The reason I have rated Negative is the lock of contact from the seller after 3 attempts to ask the same question. The file comes in 3 states. 1. full hollow helmet un sliced and good to go, ran it through 3d builder as there was something that needed fixing but no big deal, lots of files are like that. still a well designed model. 2. full helmet solid (nowhere to put your head, its capped off at the head hole and visor. 3. Separated helmet, the update that made me jump on this file as splitting this helmet is a pain and would result in loads of extra sanding. So the separated file has a the top dome of the head and the 2 side skirts split in a really nice way with registration balls for a better alignment when putting it all together and the hollow dome for your head to fit in, However when it comes to the face section this is one solid piece and is capped off top, bottom and visor. the hollow head to go with the hollow dome isn't there and due to the point where its split you cant split it yourself from the other file as it is doubled up at the brow so wouldn't fit. In short if your gonna print it full or split yourself as a helmet you can put on and are willing to do the sanding between small deep gaps go for it or if you want a separated head solid that takes up lots of extra filament to go onto a hollow cap that's cool to. Again the model is really nice but the offered separated files do not offer a separated wearable helmet. I hate to leave Negative ratings but fletchasketch3 doesn't seem to respond to customers anymore. And as the listing states resizing to fit body types and is a file for printing this implies its a wearable prop once printed. I really hope this is just an oversite by fletchasketch3 as I really like his models and want to buy more than the couple I already have. But until/if he replies It can't be printed as separated files as he's stated.
