Replacement caps for Cobra Aquila taps. These little badges are used to indicate hot or cold tap. I couldn't find anywhere I could only buy them, so I made some. They are blank on top, so you can add a H or C to it. I printed them in red/blue for the same effect.
No supports needed and 0.16mm layers are suggested although 0.2mm works as well.
The author marked this model as their own original creation.
