Parametric Nut and Bolt

I will most likely upload other nut and bolts generated from this file

The Nut thread cutaway(to prevent extra thin threads being printed on the nut) can be buggy if the nut is not a multiple of pitch.

The thread is created from the ISO standard then clearance is added - i did it this way because the built in fusion thread function is strangely buggy and intensive to run.

To match the model with actual ISO hardware the pitch for the diameter you are using will be needed e.g. for M8 coarse pitch it's 1.25 mm.

Flat bolts are especially useful for 3d printing for the added strength and ease of printing they provide.

Variables that can be changed in f3d file:

• Head Diam(Tied to nut diameter)
• Thread Pitch
• Thread Scale(For better 3d printed threads)
• Thread Clearance
• Thread Major Diameter
• Head+Nut Thickness
• Head+Nut Chamfer
• Shank Length
• Flat Bolt(Y/N)
• Head+Nut Chamfer(Y/N)
• Head+Nut Faces(Y/N)

Please Comment any bugs you encounter and i'll attempt to fix them - i might upload a second version for bolts that fit countersunk holes.
