Hictop Duale 3 Purge Bucket with Brass Brush

The Hictop D3 tends to get one nozzle all gummed up while waiting for the other nozzle to finish printing.

This helps keep each nozzle clean.

In addition, if you don't like the purge towers in your favorite slicer, you can purge into the bucket instead using the tool change script.

This uses brass brushes readily available on Amazon affiliate link below:
