This mount fits a RTK mounting rod that comes with a Mammotion Luba2 when the rod is cut before the lower female threading. Fit is mallet-tight (30.19mm) when the rod has a single coat of paint/primer. The mount has 4 top/bottom chamfered holes (I used 3-inch exterior screws) and channels for drainage. I recommend PETG as a material for its superior layer adhesion and outdoor performance.
