Bottle Cap Opener - Strong and Simple

I posted this bottle cap opener design because I saw people with openers they said fail. Printed with 1.2mm walls, .2 layer height, and 28% infill, from Filiament OutletPLA and hatchbox brand PLA, 1.75 mm with a cold bed, I have tested both styles (Penny and no metal) on over 100 cap opens (I have a bottle capper for the standard 26mm caps, not a drinking problem :D ) and the results were:
The "no metal" had some scratches at the opening surface, but nothing significant, no cracks. This may not work as well with ABS, if someone would let me know...
The Penny version had scratches and a slight bend, but no signs of failure. (I like the no metal version more)

I'm starting to sell these and bring in some cash for a decent product, feel free to slap another logo on top and sell them yourselves. All I ask then is that you comment and let me know how you do.

Thanks!
