Kitchen Aid Waste disposal plug

thingiverse

Recently, my cousin asked if I could repair a plug for her kitchen waste disposal unit. The plug has a magnet fitted to it which activates the unit when fitted, presumably to stop you disposing of your fingers whilst shovelling the stuff to be ground up down it. The plugs are no longer manufactured and hers had sheared off where the aluminium alloy handle is fitted to the nylon body. I drilled out the handle and tapped an M5 thread into it, then fitted a stainless steel screw (M5 x 40mm) with some loctite and then sawed off the head. The original nylon body of the plug had a slotted hole where the handle stem fitted, secured with a small dowel through the body. I tried tapping out a thread but it was unsuccessful, so I ended up modelling the whole thing and designed a round threaded hole to fit the M5 screw now fitted to the handle. Once tightened, a 2mm drill through the set pin hole and drift the original pin back into place prevents the screw from undoing when you twist the plug into the sink plug hole. Hope it is of use to someone else and if anyone has any suggestions, feel free to let me know.
