mo4 gas mask 3D Model

background. mo4 gas mask is tactical airsoft, which is developed and used in u.s. army since 1980. it is used against chemical and radioactive gas, but not effective enough for preservation of oxygen.

long description:
this 3d mask is have same angles and form proportionally as it made according to online pictures which shows different views of 3d mask. certain thickness to the model is made by solidify modifier, even it views like a flat 3d object. all polygons which intersect each other are fixed after applying modifiers. polygons which lays inside the mask are fixed by flipping normals on opposite direction after applying solidify modifier. the model is supposed to be applied by subdivision modifier according to the plan of making its correct 3d form, but depends on personal performance. its shown on pictures that some polygons of special pattern lays around lens in clear sequence. lens are not made. polygons on borders of gaps are cut by loop to make angles sharper if subdivision is used. the number of polygons and faces which is shown in general information of product is sum of gasmask and filters polygons, not separately only gasmask. names of objects: mo4mask, gasfilter1, gasfilter2.
the model is used for video games, but textures and special materials are not made, only simple material of white colour. probably it can be used for printing too, as it low-poly object. additionally, the project contains two different 3d gas filters for each side of gas mask.

short description:
- certain thickness
- pattern around lens
- intersecting polygons fixed
- loopcuts around angles
- flipped normals
- two 3d filters

let me know about your thoughts of how to make it in your version and performance. comment and ask questions as well. hope you enjoy it).
