Here we have the T45-d Power Armour helmet from Fallout 3, consists of 49 items and the main body of the helmet breaks into 12 pieces that are doweled together. Due to the size and shape of pieces that make up the main body some sanding may be involved to give a perfect fit. I've designed it so that the lens can just be cut from any thin tinted plastic can be inserted inside where it is held in place with locking tabs. I would want to test print this myself but knowing the fan following someone is bound to beat me to it, so if anyone has feedback on the tolerances or assembly please feel to contact me.

Update 30/08/15 Forgot to add the main dowel part that connects the helmet together .rar updated. Update 12/09/15 After having another look I've reduced the size of the ear inserts to free up more space on the inside and have uploaded the new STL'S. If you have already started printing then all you need is to reprint the following parts; HELMET BODY - MIDDLE TOP LEFT, HELMET BODY - MIDDLE TOP RIGHT, RIGHT EAR INSERT, LEFT EAR INSERT, SIGHT ARM, LEFT EAR KNOB. I have also uploaded some screenshots showing some rough internal dimension.Update 02/11/15 Added an STL of the lens so you can use it as a template for getting the correct lens dimensions.
