aquarium intern 3 chamber filter

I designed a intern 3 chamber aquarium filter with my own filter media (other file in my bio) and sponges. first chamber will be the sponge chamber, the second will be with stones or (my own) other filter media. The 3th chamber will be the chamber where the internal pomp will be.

Total size of the filter is :

202x60x202 mm (LxWxH)
