beer bottle cap

I realy like the design of kitzi85 (https://www.thingiverse.com/thing:3089043) but the "Part 2" was a little bit to fragil, so i try to redesign it stronger.

The Bottle Clip (Part1) is not modified!

The part is splitted into two parts to prevent layer transitions. Just fit press "Part B" into "Part A" - a little dot of super glue does not harm.
"my" files Part A and Part B novate the Part2 from the source.

Update:
Part A V2 fits into Part B without glue!!

Part C alias Part1 aka clip from source thing is redesigned and easier to print, because of a flat buttom ;)

Added 123D Design file with all updated parts as "bierflaschendeckel_all_v2.123dx"
