This version of the venerable crocs button adds a stronger snap half with built-in supports. I have also made the pin larger in diameter so that it will stay firmly attached after it is inserted.

• Print in PETG or ASA

• 0.15 layer height (or variable layer height)

• No supports needed

• 100% Concentric infill

• 3 perimeters

• 25% perimeter-infill-overlap

Insert the snap and pin into your Croc as shown, use e flat surface like a table corner to push the pin into the snap until it clicks together. It should not come apart, and no glue should be needed.
