So you have a Yamaha MusicCast Vinyl 500 (TT-N503) and the little thing that locks the tonearm into place broke off? Mine did! I recreated it, and the result turned out surprisingly well. It fits really well and the tonearm sits perfectly still.
I printed it in Prusament JetBlack ASA. JetBlack PETG also works, but is more glossy.
I mounted it with a a black 11mm long M2.5 screw.
