I have remixed this cyclone THINGIVERSE 1447214, to use on my CNC machine. I needed connections for standard 2.25-inch vacuum hoses a small capture container with a wide mouth.
I made the cyclone from PLA with 6 layers and 30% infill. It is overbuilt and five layers with 20% should be enough. The remaining parts where 20% and 5 layers. The PLA makes nice threads, but they need working together for a smooth fit. The mason jar threads fit perfect with the peanut butter jars on the first try.
The mason jar was a remix from CANNING JAR LIDS - THINGIVERSE 19105. I chose canning jars because they are readily available in grocery stores in durable translucent plastic. Mine comes from peanut butter jars. I have made an adaptor for small and large jars, so you can choose the size jar for your needs.
This cyclone does not attach at the base (which is an advantage) and so needs to the hanger. The hanger is printed from PETG, 5 layers 20% infill.
The vacuum part took 70 hours to print and is the only part needing supports. Printing time: cyclone part 30 hours, hanger 20 hours, jar adaptor 6 hours. It is a long print; be for me it was worth it.
