Colin,
This is amazing work. Thank you for detailing this so clearly for anyone looking to do a BS Helmet Conversion. Also, thank you for sharing the tears and traps on Thingiverse.
This is true for the Kenobi series helmets and likely several other helmets being used on set today. So kudos for including in in your build.
However, I know you and I discussed this previously on FB, but for anyone thinking about cutting up their helmet, just be aware that the vented traps weren't the case for all the helmets during the filming of the Anthology movies or even The Mandalorian series. Several of us vented the traps as you've detailed (which was is a pain in the butt) but I'm still trying to put my finger on when the prop designers made this feature "standard issue."
Here's Mr. Missing Trap from The Mandalorian. Notice the solid white piece where we should be seeing vents:
Personally, I think it's because several scenes from Kenobi were filmed on location which may have required additional comfort. Regardless, if done correctly, like you've done, either way should be acceptable.
Overall, great job on the conversion. This is awesome work.
