My treadmill was missing the entire closing latch assembly. I ordered what I believed to be the full part but upon arrival discovered it was just the pin. Rather than attempt to find the part I designed a housing for it. The finish is a bit rough. I upped the extrusion flow to ensure strength. Ugly but functional. It's a pretty niche part need but I hope someone else finds this useful!
