Mason Jar Negative Pressure Bracket

Turn a mason jar into a fun negative-pressure aquarium add-on with this printable support bracket. The design holds an inverted large mouth Mason Jar at the edge of your tank, creating an elevated viewing area for fish while keeping the setup supported and stable.

Great for betta tanks, small aquariums, planted tanks, and unique aquarium displays.

Includes printable bracket pieces, support arms, and screw-style locking parts for securing the setup to the tank rim.

My betta absolutely loves it. Any time I approach the tank, he swims in to show off to me.  :)

Features:

• Designed for large mouth mason jar
• Rim-mounted support bracket design
• Both left-hand & right-hand versions included
• Adds a unique elevated fish-viewing area
• Great for betta tanks and small aquariums with 5mm glass
• Support arms help keep the jar positioned securely

Important:
Always make sure the jar remains open to the aquarium water and never traps a fish without access back to the main tank. Monitor your fish to make sure the setup is safe and stress-free.
