If models are way too small or way too big, try scaling them up/down by multiples of 10 (100% -> 1000% / 100% -> 10%)
The models should be working, but this issue has happened before so just in case.
Here are files for a helmet that combines wear in Half Life Alyx.
THIS HELMET IS SCALED FOR ME (195cm) RESIZE IT IF NEEDED
(100 / 195 x "your height in cm" to get the percentage you need to scale the helmet)
You'll also need this model for the neck ring https://www.thingiverse.com/thing:5991259
This is the most accurate free model available, maybe even most overall.
I used the game file from Alyx and upscaled it so you can print it, because of that the proportions of the helmet are as close as they could be. A lot of the detail i had to make from scratch because most of them were made with texture and bump maps and not 3d shapes.
These files are properly rotated and ready to print!
If any of the parts are missing let me know!
Some models are super unoptimized in their size because I suck at model making

08.08.2022 - added a new version of the side filter with a better shape and two other files
25.04.2023 - finally added rest of the files
16.06.2023 - fixed scale of some files, they have 2 at the end of their name, their upload date will also be different
13.01.2024 - added an image that explains which part is which for the "sliced" files for the shell
27.01.2024 - added the model for the hexagonal mesh used in the eyes
The eye border is at an angle to help getting a smoother shape.
I included not sliced bottom and the top of the mask if you want to do it yourself.
Side filter is designed to be held by two 5mmx5mm cylinder magnets. These however don't hold it very well, I'll be uploading an additional support model that you can glue to the filter itself.
