Milk Bottle Stopper Clamp

thingiverse

This clamp secures rubber stoppers firmly in place within 1-gallon glass bottles used for brewing purposes, preventing fresh wet stoppers from rising out of the bottle due to their buoyancy. The clamp's design allows it to slide smoothly onto the bottle with a secure grip and provides easy access through the top for airlocks, minimizing disruption during attachment or removal. A cut-out feature ensures that neither the stopper nor airlock is disturbed during this process. An OpenSCAD file is available for customization of the clamp's design.
