The new mod that I am basically finished creating basically turns the Lowrider 3 into a hybrid between a LowRider3 and a LowRider 2. It might be possible to adjust it suited to allow you to have those gear rails on the outside edge of the table facing outwards, sideways, with the Y motor positioned on one of my secondary Y plates. Here’s a link.
I’m currently doing it on only one side but it perhaps could work for both sides or maybe one side with something else on the other.
