Air powered aquarium filter

Low noise aquarium air filter. Probably not a great choice as someones first print, there are some things you have to do right when slicing this.

Primarily designed for using with filter wool, and a few stones or similar in the bottom to weigh it down, but you can use whatever filter material you want.

The container is a PET pop bottle. The base and the "brim" has to be printed at the same time, placed at the same place when slicing, and with a few different settings. You can scale the brim in X and Y to make it fit your bottle.

It is designed for a 20mm outer diameter pipe, you will have to adjust the base and the lid if you use a pipe with a different diameter.

The base+brim part is actually the only really essential printed part, the rest is nice to have, too bad that part is the one that is a little bit tricky to slice.

If you have trouble adjusting some part/parts to pipe or bottle of other dimensions tell me, and I might do a version for that dimensi
