Air stone set for 4mm tubing (two variants)

🫧 AquaBubbler Duo – Air Stone Set for 4mm Aquarium Hoses

Perfect for 4mm air hoses!

These practical AquaBubbler (also known as bubbler stones) were specifically designed for use in aquariums and can be easily connected to standard 4mm air hoses – especially the common green, transparent variants

You get two versions in one set:

• FineBubbler – for particularly fine air bubbles, ideal for increasing oxygen levels with quiet bubbling
• PowerBubbler – with larger outlets for more powerful bubbles and stronger current effects in the water

Both variants are compact, easy to print, and can be swapped out as desired. The design is round, robust, and functional – ideal for nano or standard aquariums

⭐ Optimized 3MF Project File

You receive a .3mf project file that can be loaded directly into Bambu Studio. Both variants (FineBubbler & PowerBubbler) are already optimally placed on the print bed and configured for fast, stable printing

🔧 Recommended Print Settings

• Material: PETG (strongly recommended) or PLA. PETG is better suited for permanent underwater use
• Layer Height: 0.2mm
• Walls: 2
• Infill: 100% (Solid material). This is important so that the stones sink safely and no water can get trapped in the infill
• Supports: No supports needed
