algorithmic modeling for Rhino
Here are three grasshopper documents for generation thread screw
The scripts just generate surface with or without problem on joints. I did 1 turn RailRevolution with n threads profile. It seems not better with n turns with 1 thread profile.
thanks, it work fine
Just wanted to say how great this is, very helpful. Thank you!
I had difficulties to make solid, but it work fine with your script. I discovered new functions.
Here are scripts for GH 0.9.0056. I will try to make them solid.
What are you using to rendering those? They look great. Care to share any settings or tips?
I dit some more modifications:
- Interface: select target surface,
- Measure the length and diameter,
- Changed the procedure to handle partial turns,
- Add champfers,
- Place solid @ selected surface.
And i made a knurling script, based on this movie: http://grabcad.com/library/knurling-on-shaft
Kind regards, Peter Kompier.
How does the male female work? It seems like the surface are directly on top of each other. I am trying to use this for 3D printing. It seems as though the tolerance would be to tight for the threads to actually work.
What do you think?
I've done a lot of 3d printing where I print the threads of screws. This usually works really well. I usually download a model of the specific screw I intend to use off of McMaster Carr (http://www.mcmaster.com/). For the female side, you can download a hex nut and match it to the screw threads. They usually include various formats for the model that you can download (.igs, .stl, .obj, etc). You could check your models against these screw/nut threads to check for accuracy. Just a thought.
Thanks Andy. Yea, That make total sense. I completely forgot that McMaster has models available. I'll give it try.
