⬢Changes in the RC2 version (compared to the RC1):
⬢Increased wall thickness (slightly stiffer and more durable)
⬢The headband is no longer printed compressed - Lower pressure on the temple.
The visor was moved further away from the forehead - This allows a better fit over bigger respirators and protective goggles.
⬢The printed part now has an extension for the visor (the visor curves less than the headband).
