A 3d model of the helmet of subject delta from the Bioshock games made by commission the model is designed for printability and has slots for LED's as lamps - the window and lamps can be covered with 3mm plexiglass cutouts the full helmet is about 60cm tall but can be easily scaled and remain well printable I also added a version where the screws on the rim are separate pieces with fitting holes to glue them in as well as one precut into 24 parts with extreme mesh detail
