Betta Fish Resting Leaf

Bettas love to take a rest while living in your Fishtank. Often they will find a lead to lay on.

Why not print your own leaf from a Aquatic-safe filament?

Just add a suction cup. The Suction cup slot Diameter on mine is approx 6.6mm in diameter with a slot depth of approx 3mm. 

Factor in layer strength for where the suction cup connects.
