The file 'Nikon To Telescope Adapter 3D Printer Model' is (step,stl) file type, size is 338.2KB.
An adapter to fit your Nikon camera to a telescope with a 1.25" barrel.
Because the 3D printed plastic is probably too weak to carry an expensive & heavy camera, you must strengthen it with a piece of metal tubing. Outer diameter of the pipe should be 29 mm, inner not much smaller than 26 mm. These were the dimensions of a piece of bike tubing i had laying around.
I attached the step file so that it is easier to adjust it to other dimensions.
