Listerine mouthwash always drips from the bottle and makes a mess on the shelf. You could be careful to wash the cap after use, OR print a work-around!

This clamp-on device is designed to collect the drops that'd make a sticky mess on the shelf. It's designed for the larger bottle of Listerine. You can use the OpenSCAD file to adapt it for the smaller one.

This is my first print of a model I designed myself, I think it turned out OK. It fits the bottle perfectly. The walls could be made thinner to speed up printing, it can be customized in the scad file.
