I designed a bottle opener in the shape of a '6'. There are no sharp corners where your hand is on.
The rounded shape is also very strong as opposed to
...显示更多 right angles.
The opening for the coin has also some chamfers at one side to avoid right angles and make it stronger.
Earlier designs breaked at that point while removing a cap from a bottle.
I used only 20% infill, but i printed it with 5 outline layers to create a strong object.
IMPORTANT: This bottle opener works with a (€0,20) coin with an outer diameter of ø22.20mm and a thickness of 2.1mm.
