3D Printed ESAB Warrior Tech Helmet Hinge Latch Plate

My TIG welding frustration suffered more than usual the other day . 

I have an ESAB Warrior Tech helmet which works really well when welding but it would not stay flipped up when I wanted to see things in daylight.   Every time I leaned forward the helmet would drop down over my eyes and thump me on the chest.  Added to the fact I was trying to TIG some thin wall tubing I was no in no mood for distractions.

Before the helmet joined the happy hunting ground over the neighbours fence I took it apart to see why the latch up action was not working.   Inspection revealed that the backing plate had cracked around the latching cam.

I could have bought a completely new head band assembly but the part in question might just be 3D printable.   The Fusion 360 sketch ended up being very complicated based on eyeball guesses on curves and centres but on the second version I had a printed replacement which did the job …. for the time being anyway.

If anyone is suffering from a bruised chest let me know and I will forward the Fusion file.
