Simple Two Piece Design
The helmet itself is comprise of a front and back piece. The back piece doesn't require supports while the front only supports internally meaning that you should have a nice smooth print on the outside. This of course always depends on your print settings, more than likely both pieces will still benefit from supports.
The model also contains two alignment pins that allow for easy alignment and glueing of the pieces together.
Visor Insert Features
The inside of the helmet features Guides to hold the visor in place. While the visor can sit on these alone I would recommend a low strength glue or tape to help fasten hit while still allowing you to remove the visor.
Model includes a sizing ring to help you scale the helmet to fit over your head. Sizing ring is a equal to the size of the throat of the helmet so make it so you can fit your whole head through without slicing your ears off.
Full Visor Resin Kit
This model includes a full kit to help you make a rubber mold capable of casting a resin visor. A resin visor in and of itself will have some reflective properties while more importantly allow you to make the visor see-through and a color of your choice. It also allows for more complex geometries than vacuum forming and makes for a sturdier visor. The visor, baseplate, and mold shell all fit together to ensure that the the model only requires a minimal amount of rubber. The less rubber required, the less it costs and the more reusable the mold and easier the demolding process. Model also features a mold stand so that you can ensure the mold can be filled to the top without deformation when you pour in the resin.
Visor Resin Volume: 91.7 mL
Visor Rubber Mold Volume: 391.3 mL
