Longneck Bottle Coaster - Snap-Fit, Stackable & Recognisable

A friend of mine always forgets to put his beer back on the coaster so I designed a coaster which stucks onto the bottle. This design only works for Longneck Bottles, 330ml. Through the different patterns you can always recognise which beer is yours. The raised rim prevents drips while drinking and the coasters are stackable.

The model can be printed without support. Just make sure that the wall thickness is 1.5mm or higher, to prevent the Snap-Fit from breaking.
