Wine Bottle Screw Cap

A screw cap for a standard 750ml wine bottle. It should be water tight directly from the printer but I found removing the plastic liner from a commercial cap and placing it inside the printed cap works really well.

Two versions (with their corresponding FreeCAD files) available. First version can be printed and used as as is. The basic version will also work as is but I've removed all the "fillets" and "chamfers" so there will be some sharp edges. The basic version is best if you want to make some edits to the FreeCAD file.
