No Support needed, see picture for orientation of models. Make sure lay shaft flat. Can replace shaft with metal M8 screw for more stiffness.Adjust length by adjusting screw in amount or cut off the shaft as neededAdded hand tight nuts as needed. Can add to bottom of handle and/or top of ball to help fix the length. Likely not needed if your printer prints dimensionally correct. Can add grease before assemble to increase smoothness.
