Mason Jar Canister Filter
thingiverse
I had a hard time finding a canister filter that was small enough, so I decided to make my own. To create a seal, you'll need to silicone the bottom rim of the lid and around the plug opening where the USB cord goes. This pump works well: https://www.amazon.com/dp/B076MX9V8M I used this silicone tubing to connect it: https://www.amazon.com/dp/B07B5XK6RY On top, I added some filter media along with a coarse sponge. To keep water from leaking out, I printed the canister with triple walled layers and triple bottom/top layers.
