Fluval filter basket with 4 chambers

This is a remix of https://www.thingiverse.com/thing:6267303 basket. This basket comes with 4 chambers and I made it 1mm smaller on X and Y axis for better fit. To use 4 chambers, print 3 upper dividers and 1 bottom one. I actually ended up using it as a 3 chamber basket. Top chamber for a foam and floss, second chamber is for activated carbon, and bottom 2 chambers are used together as one big chamber for mix of ceramic bio balls and tubes. Print it slow in PETG. No supports.
