Soda Bottle Cap Knob

thingiverse

Makes it easier to open and close 2-liter soda bottles. Remove the raft from the cap. Heat up the material to create a custom fit if needed, and scale the design for your specific requirements. Securely attach the pieces together using glue. The inside diameter of this design is slightly tapered, providing a snug fit with standard 2-liter soda bottle caps. The T-handle attached to the pump handle is glued in place, ensuring a secure connection between the two parts. Before assembly, sand both contact surfaces for optimal performance and longevity.
