Basic fishbowl filter

Basic filter for a fish bowl.
Since there is not much space in a bowl for a filter, this one is designed to keep majority of it above the water, only pump is submerged.

This filter is designed around cheap 2$ water pump from Aliexpress, wont leave any links but you'll find it easily. It can accommodate any pump smaller then 30mm height and 28mm wide.
You can put regular kitchen sponge as filter, but it is better to use real filter medium or print one.
Designed for bowl opening of 147mm, if you want smaller or larger, you just need to modify front_holder.

Print settings:
PLA/PETG
0.2mm layer height
Holders only: print with 4 layers as they might need strength.

Keep in mind that small bowls like this aren't ideal for fish, but sometimes that's all people have - so this filter is just meant to help fish live a better life. The filter provides filtration, and because of the water drop, it creates ripples and a flowing stream that helps push oxygen into the water.
