I would like a 52mm diameter x 0.75mm pitch male thread and its mated female threaded hole. It is for a camera accessory. The male and female threads must be watertight for 3D printing. The female threaded hole should be 3.75mm high or 5 turns. I should have a 2mm border encompassing it. To design it, the threaded male solid can be inserted into a 56mm diameter x 3.75mm high cylinder and "subtracted" to make the female thread. Unfortunately, I don't have Sketchup Pro so the Solid Tools Subtract option is not available to me. The male thread should be 6mm high or 10 turns. I would like the file in sketchup format so I may add it to my model. I will pay half up front and the remaining half upon successful printout and mating of the parts. Any questions please email me.
