Brewing Blow-Off-Tube Caddy
by ComradeQuiche, published
If you have ever brewed beer before you may have needed a blow-off-tube to stick into the top of your fermenter. This tube, and chamber acts like an over sized airlock that will (Hopefully) catch any excess foam and liquid that may have sprayed out due to vigorous fermentation.
Why print this part? Well if you have used a blow off tube, then you have probably taped a length of tube into an open vessel full of sanitizing solution, hoping the whole thing doesn't fall over and spill everywhere. It is also a pain if you ever have to move the fermenter since its has a length of tube precariously stuck into the top of an open vessel like a cup or bowl.
The main reason I made this caddy is because I have a cat, a very curious one! I sure don't want to leave an open container of sanitizer out, and even if its somewhat sealed, he could knock it over. But not any more! Print these two parts, buy a few rubber bands and a ball jar, and keep your fermenter setup nice and organized.

The only overhanging features are the little posts where the rubber band gets pulled on to. I printed it with a Makerbot 2 and used "External support" It simply printed a tiny little amount of support material up to that point to cradle the posts. Any machine that prints support should easily be able to do this.

Once you have it all in front of you do the following:
- Pull the large rubber bands through the printed caddy.
- Stretch the large rubber bands and caddy over the glass fermenting jug.
- Screw the printed cap onto the top of your ball jar, then insert the plastic tube into the top, making sure the tube is about an inch from the bottom of the inside of the ball jar.
- Stick the other end of your tube into the top of the rubber stopper, then into the fermenter.
- Attach the ball jar to the caddy using 3 normal rubber bands to secure it.
- You are done! Now no pets should be able to knock your setup over, or spill it, and you can easily move it!
