Mason Jar Canister Filter

Couldn't find a canister filter quite small enough for what I was looking for, so I made my own. You'll need to silicone the bottom rim of the lid to create a seal as well as around the plug opening (used for the usb cord).

& topped with filter media as well as some coarse sponge.

Printed triple walled as well as triple bottom/top layers to help keep it water tight.
