I designed this filter to clean the water in my aquarium.

Contents

• the body (tube)
• two filter caps
• two hose mount tubes (hose connectors)
• six filter grid items
• four grid spacers
• three makeup pads

All but hose mount connectors are printed without supports.

Assembly

1. Give all threads a little bit of oil. Make sure you can easily screw/unscrew the filter cap and all hose mount connectors.
2. Screw one filter cap on the filter body.
3. Put a spacer ring inside of the filter body.
4. Make a sandwich of one grid, one makeup pad, and one grid.
5. Put this sandwich inside the body.
6. Repeat 3-5.
7. Screw the remaining filter cap.

It happened so that three makeup pads are quite excessive for the purpose of cleaning the aquarium water. One is just fine.

You can use either of two methods to print grids:

• print the grid.stl from the archive (slow)
• use Cura slicer and add grid_overlap.stl + grip_simple.stl (fast); mark grid_overlap model as an overlap model and merge it with grid_simple (see the screenshot)

Thread clearance must be something around 0.2 mm (Fusion360 default + manually added additional clearance of 0.1 mm). Depending on different print settings you may want to give threads a little bit of filing with a small triangular file. To make it able to keep up with higher pressures fill joints with some Teflon tape.
