Prusa XL Mod - Nozzle Seal Spring Blunted End

Some of the Nozzle Seals on my Prusa XL had broken and i was thinking that it could be the spring steel was too sharp and was cutting the silicon seal. 

This model blunts the end of the spring steel to maybe stop the silicon seals from breaking/getting cut..   

I have just installed, had to work them a bit to get them on, but fit well. They have not had any long term tests as of yet.

Printed at 0.15mm layer height in PLA+.  TPU would probably work well, but I haven't tested.

Print vertically, no supports.  I didn't need a brim, but they have very little contact area with the bed, so it could be needed.
