Easy-Print Filter (Mason Jar) for 0.25 in / 8mm ID Aquarium Tube

thingiverse

A Simple Design ================ 1. Print two copies of this design and place them on top of a standard mason jar. 2. Fill the jar with your favorite filtering content, such as cotton or a washable cloth. 3. Add an inexpensive submersible power head, inner and outer tubing, and enjoy transparent cleaning results. We have many similar designs available - If you like this one, we'll share more! Notes ----- The valve stem is designed to fit standard aquarium tubes with an ID of 1/4 inch (8mm) and a 3/8 (10mm) OD. * I'm always impressed by the effectiveness of simple washable cotton or cotton-poly washcloths. * If you don't have any pet invertebrates, filtering through natural copper scouring 'scrubbies can destroy algae as well as all your invertebrates. * If your aquatic life is copper-tolerant, put the scrubbie into a cotton sock and wire it around the internal out-flow tube. Fake Copper Warning: Be aware of cheap copper pads! Real copper is not magnetic. 100% natural copper pads will also not release chemical dyes & toxins into your water. We get what we pay for - When in doubt, soak that pad overnight in water to test it first! If you can't find a genuine copper pad, visit your local hardware store and pick up some bare copper wire. p.s: I added "the basket" to use inside of a cotton washcloth / wadding strategy - keeps the out-tube from pulling-out the threads. Some mason jar lids rust - If yours are rusting, try the next design @ https://www.thingiverse.com/thing:3543847 I also added a remix of https://www.thingiverse.com/thing:1323393 to provide some rust-free aqua-action on 2019/04/07.
