Down the street there is an amazing loose leaf tea shop where I source my favorite blends. To brew my tea I like to use a Bonavita Immersion Dripper. The dripper is very elegant being made mostly of porcelain, it seemed like a reliable and durable piece. Unfortunately the base and in mechanisms are plastic and one day a small, but critical, plastic arm snapped.
Normally this would be the end for the entire piece of hardware and the entire thing would need to be replaced. Luckily the bottom is easily removable and small pieces of plastic can be 3D printed.
With a little over 30 minutes of modeling and printing I had a design that fit and worked well. I decided to change the design and move more the the torque to be around the metal screw points instead of the plastic pins. I think this new piece should be much stronger than the original, but I might reprint it it more neutral color.
