The Most Customizable MJOLNIR helmet ever designed

This helmet comes with 12 optional attachments and can support up to 7 at any given time. This allows the Firefall helmet platform to support thousands of different combinations. This helmet can support the following:

- A suite of Picatinny rail compatible side attachments from Halo: Infinite and Halo: Reach

- A flat, universal overhead mounting plate

- Multiple UA attachment upgrades

- A suite of legacy ODST attachments

- Multiple removable vent covers

- The Unique Mk62 CBRN Module

 All attachments are connected to the helmet by rail, 3d printed screws, or by magnets. Attachments requiring magnets will require 20x3mm disk magnets. These magnets are supported all the way down to 85% scale. This means that not a single drop of glue is required to assemble this helmet and that you will always be able to disassemble and reassemble with new exciting customizations.

 This helmet comes with two common types of connectors in order to assemble the majority of the helmet. There is a master screw that comes with multiple side holes through which a small Alan wrench can be used to drive the screw. The holes in the top can also be used in conjunction with two small tools in order to spin the screw. This design was chosen as opposed to a typical hexagonal Alan key fitting as it prevents the deformation of the 3D printed plastic under the stresses of a singular twisting Alan wrench. You can view my personal assembly video to get a better understanding of the advantages. These screw allow the helmet to be securely assembled without any need for glue. The second common connector is a master peg. This common peg fits in every screw slot to make for a quicker an easier connection for quick helmet assembly and disassembly as well as a alignment tool if you do decide to glue the helmet together.

 ODST Legacy Bucket

Also included, is an alternate legacy bucket that allows for the helmet to more closely resemble the original ODST helmet as it appears in Halo 3: ODST. This can be combined with all the legacy attachments to be able to recreate an updated Firefall variant of all of Alpha-Nine's helmets.

This bucket is also compatible with the UA visor attachment.

 Magnetic Sealed Helmet

This helmet is comprised of a main bucket that closes around the head at the nape of the neck utilizing a magnetically attached neck seal. This neck seal supports 5 10x3mm disk magnets. The helmet will support these magnets all the way down to 85% scale.

 Active Ventilation System

This helmet features two, side-mounted air intakes with internal fan integration. Each of these side vents come with optional vent covers for standard air flow, increased airflow (Dutch's vent covers), and closed air intake via the MK62 CBRN Module. The standard vent covers slot into the side of the electronics suit and rotate into place. They are held in place via a singular 10x3mm disk magnet, cordage, or a nut and bolt. The 10x3mm disk magnet is supportable down to a scale of 85% The internal electronics suite features a spot for a 40 mm fan as well as a 45 mm fan to provide airflow through these ducts. These two cavities are meant to allow for more flexibility in the size of fan that is used after scaling the helmet. For example, my personal helmet was scaled to 95%, so the larger fan slot was still able to take a 40mm fan. Additionally, there is a dedicated channel that leads to a rear battery pack located in the base of neck. The battery pack slot should be able to support either a 9V battery case or a dual AA battery case.

 There is an additional overhead vent to allow hot air to flow up and out of the helmet.

 Internal Audio System:

Also located in the internal electronics suite is a casing for a 40mm speaker. There is a speaker cap that will slide over the speaker to keep it in place. Both the cap and the housing itself feature a circular channel to snake through the speaker wires such that they can be snaked through channel in the base of the neck with the fan wires, or such that they can lead through the bottom of the helmet where an auxiliary cable or external audio source is located.

 Scaling Templates:

This helmet comes with multiple scaling tools to ensure a perfect scaling for your new helmet. The three scaling rings slot together to form a skeleton that can let you know intuitively how the helmet will fit and how much clearance there will be between your head and the helmet walls. The entire ring may only take 2-3 to print and will save you many more hours in total printing when you can rest assured that you will get the perfectly scaled helmet during your first attempt.

 Multiple Visor Options

There are multiple ways to go about fabricating complex visors such as the Firefall's visor. I included several files for different methods of fabrication for varying levels of experience. I have included a visor buck for those interested in vacuum forming, a thin shell version of the helmet for those interested in resin printing the visor, and a standard visor model for those looking to make a resin visor via mold. Additionally, I experimented with a two piece visor template system that will allow for a cheap, quick, and effective way for beginners to fabricate their own visor. See my assembly video for more info on how to turn these templates into visors. Whichever you pick, the visor is kept in place by slots and tabs that fit within the walls of the helmet itself
