The tonearm on my turntable broke, so I printed a new one! This is specifically for an SME 3009 Series III Tonearm. This was kind of a pain to model and print, so the fitment might be a little off. I reduced the tolerances on the holes from the one I printed, so it may work fine for you, but things might still be a little tight and you'll need to bore out the holes or sand things down. I've included the 3mf files so you can make adjustments.
Print with supports.
