Z axis dewobbler for Cupcake/Thing-o-matic

Since I've opted to resurrect my cupcake and have found the most popular Z-stabilier has gone 404, I've designed my own. So far I've installed one of these in my machine and it has definitely improved my prints a fair bit. I suspect installing a second one will go a fair distance further, as with one installed I suspect the z-stage can pivot about the rod. I found a suitable rod and a hollow pipe that fits the rod very very tightly at a local RC model shop.
