This is an adapter for dust collection of the Rikon 10" bandsaw. It may work for others as well. The stock dust extraction leaves a lot to be desired. The guide bearings under the cast iron top got jammed with dust. I decided to collect the dust right under the table. This fits snugly between the bearings and the table and hooks up to a 36mm dust hose. Using this extractor with a perforated zero clearance insert ( https://www.printables.com/model/708395-10-rikon-bandsaw-zero-clearance-insert-model-10-30 ) eliminated all the dust under the table and sucked up most of the dust on the top as well. Use (4)8x3mm magnets to mount (optional) Print with Organic supports printbed only (maximum branch angle 10 degrees). Happy Printing.
