Beer bottle opener (whistle, key-ring, magnet)

The Australian 5 cent piece print and play.
Designed to rip of raft like a band-aid and crack a beer each time. Complete with whistle, fridge magnet and key-ring hole.

Print settings
2 shells.
15% Infill.
No Supports needed.

Public Note: After trial and error
I believe strength comes from the 2shells around key-ring and magnet hole in mesh and not the infill % .

Personal Note:
Whistle works extremely well but people do not come running with beer!
