CO2 Cylinder Protector Cap | Snug Fit

BOM: Printed with ROSA3D PLA Starter Light Blue

Lost the original cap for your sparkling water maker's CO2 cylinder? This simple yet incredibly handy protective cap shields the soft brass threads of your canister from damage and dirt. It is an absolute must-have when you're tossing an empty cylinder into your backpack or grocery bag for an exchange.

The model features a sleek, subtly rounded square profile and is designed with precise tolerances for a satisfyingly "snug fit" directly over the valve. It perfectly accommodates standard screw-in cylinders (SodaStream, Dafi, Brita, Philips, etc.).

Key Features:

• Satisfying Snug Fit: Engineered to push onto the valve with just the right amount of friction so it won't pop off in transit.
• Thread Protection: Keeps the delicate brass threads safe from dings, scratches, and debris.
• Universal Compatibility: Fits standard screw-in CO2 cylinders used in most popular home carbonation systems.
• Premium Look: Print it face-down on a textured PEI sheet to achieve the beautiful, rugged top finish shown in the photos.

Printing Instructions:

• Orientation: Print completely flat, upside down (with the solid top surface touching the build plate).
• Supports: NONE. The simple cup-like geometry prints flawlessly without any support material.
