This drying/storage rack works great for your 3-cup moka pot. I imagine it will work fine for any 3-cup Bialetti or similar moka pot, but I made it based on my Bialetti Kremina 3-cup moka pot.
I printed in PETG with a fine layer resolution for easy cleanup. Black worked out nicely since it hides any coffee stains that could be present on the stand.
