Bioball 5cm

Bioball for biological filter for aquariums or ponds. Inside the ball you can place a piece of thin sponge or synthetic cotton to improve them.

These bolan are prepared to be able to close them with 1 or 2 flanges and also with 2 or 4 3mmx10mm wood screws.

Recommended not to print on biodegradable filaments such as PLA. Preferably natural colored ABS or PETG (no dyes)

The bioballs v2 have a weight of 21gr (24gr with supports) and walls of 1.6mm.
The bioballs v3 have a weight of 11gr (14gr with supports) and walls of 0.8mm. I recommend the v3 as they use less plastic and are strong enough.
