Bykski Pull Drain Valve

grabcad

I don't own one of these (yet) so this model only shows the exterior appearance with measurements taken from the product page (https://www.bykski.us/collections/drain-valve/products/bykski-g1-4-female-to-female-pull-drain-valve-black-b-hp-dv). I have no idea how this works or what it looks like internally. Maybe I'll redo the model once I have one and can figure out the internals...
