This is the first 3D print layout. The three nuts are different sizes becuase 3D printing is a collection of linear movements so the surface
is not curved. Different sizes have to be tried to get the best fit. The female threaded nuts are changed to find the best fit with the least
amount of waste.
The male will come through to the end of the nut thread shown above. The goal is for the male thread to be even with the surface of the female thread.
Not inside or outside, but even as shown in the above drawing.
3D printing is a collection of linear movements, so the surface is not curved. Different sizes have to be tried to get the closest surface contact. There are 5 female nut threads Nut A:+0.005"; Nut B:+0.010"; Nut C:+0.015"; Nut D:+0.020"; and Nut E:+0.025". The middle nuts B, C and D are suggested. Experience has shown the 0.015" of Nut C will be the most common one to work, but different machines and different resolutions .
