Overview
A minimal, highly practical magnetic holder designed for aquarium CO2 diffusers with a stem/tubing outer diameter of up to 4.5 mm. Unlike conventional push-through holders, this mount features an open snap-on clip design. This allows you to easily attach or remove your diffuser for cleaning/maintenance without disconnecting the CO2 tubing! (Use magnets as described below)
Key Features
Easy Maintenance: Snap-on design lets you snap the diffuser in and out in seconds.
Fully Encapsulated Magnets: Magnets are completely embedded inside the print using a layer-pause, preventing rust or water contact.
Optional Permanent Glass Placement: The outer magnet piece can optionally be taped/glued to the outside glass using double-sided tape, ensuring the diffuser is always reinstalled in the exact same spot after cleaning.
Flexible TPU Fit: Designed for TPU to provide a firm, scratch-free, high-friction grip on delicate glass stems.
