Leg clip for Black & Decker Workmate

This is for the B&D Workmate - Dual Height, with the little extension legs, as pictured.
They have a plastic clip which holds the legs open/closed.
They are badly designed and break when perished.
So here is my replacement.
They are a PITA to fit, needs a bit of finangling and filing/smoothing, but they work.

Update: Still a terrible design, even my replicant broke after a year or so weathering, but at least I can print replacements...
