Wall Bottle Opener (without metal)

This is an experimental bottle opener, I printed this in PLA, so far, so good.
There are two versions, one you should pull your bottle, and in the other you should push them.
Let me know what you think, experience and you considerations to improve that design.
If you like this bottle opener, or it is useful to you! Consider buy me a beer (TIP button at left), this way I can stay testing and improving the design, LOL!
Finally, thank you Leemes by the original one.
