[Plugin] EP_Fasteners. Creates 3d printable threaded UPDATED

cotty

Nice video, will have a look at the plugin asap, thanks for sharing!

Bob James

Does the fact that some of the results have reversed faces have any impact on printing?

Dave R

Very interesting tool. I can see that being useful for a lot of things.

Bob has a good point and question about reversed faces. In your video, when you made the Phillips head screw, there were reversed faces on the head. On the underside of the head it appears there's also multiple co-planar faces z-fighting.

Is there a way to increase the number of sides in the circle to make smoother threads?

Oxer

Interesting plugin but in OS X & Sketchup 2015 64bit the EyePhysics Fastener Menu window is empty, nothing in Ruby Console.

I have not downloaded the plugin yet but looks like it could be very useful.

Would like to see options for metal and wood screws.

hi Jay,

as Oxer points out none of your html will show on a mac...

The primary reason is you are using 'non' ruby, window only paths...

If I change for e.g. to

 @@HTMLFile = File.join(__dir__,"HTML","EP_Fasteners.html")

they do work on a mac...

Once running 'thru holes' work but the plugin fails at the build stage for any with thread detail...
It 'beachballs' i.e. 'freezes' at this step...
goes no further, SU must be 'force quit'

That was why I zoomed in on it in the video. That was not normal. The build process is careful to order the faces correctly. I believe I may have an error on the 1/2" coarse specification.

Thanks!

Hi John, Thanks! I haven't tested anything on Mac. I will modify the HTML entries and repost. Perhaps with all of the html correct, it will run for you. If not I would be very pleased if you could help me isolate the problems!

Thanks,
Jay

Here is an Updated Plugin **(v1.0.1)**with the phillips head faces corrected as noted by Bob and Dave, and the HTML paths updated as described by Driven, so they should work on Macs too...

Thanks! Jay

v1.0.1

Dave R

Thanks for fixing the 1/2" bolt. It looks like the nuts could use some attention, too. Top faces are reversed at least on the 1/2 and 1/4 in. nuts.

What about making the threads smoother? Any chance for an option to adjust that?

The HTMLs work now on Mac but when you try to create some element it appears a error message in Ruby Console, here the error messages:

And the EyePhisics Fastener Menu window isn't refreshed automatically when you reopen it, see the image below.

This will reset the dialog on a mac

      @@dialog.show()
      @@dialog.execute_script('location.reload(true);')

The issue I have is with threaded thru holes, both breeds...
the first threaded thru hole takes minutes [many], a second of the same is instant...
a change in the params will revert to slow-mo...

BTW: what are the observers for, if possible it is best not to have them on mac SU...

Jay,
also, both the above error messages contain commas as decimal separators, so I assume your code isn't handling them...
there are some posts in the developer forum on the topic...

Hi, the Observers are what let it create the 2nd component and glue it to the 2nd face. Otherwise
I couldn't let you use component place to set the first hole location.

Part of the speed issue is creating all of the geometry in one Geom::PolygonMesh. When I tried just calculating one threads worth and duplicating it offset by a thread, the results were not as good... but it was much faster! I expect that this can be faster, and if there is enough interest, i will try to make some time to work on it again.

Ah, Thanks! Now I feel provincial.
I am stuck in the U.S. mindset for decimal places.

I will go back through the code and try and find all of the decimal place biases I've put in.
Please accept my apologies! I will post another patch in a day or two, if you would be kind enough to test it again after that I would appreciate more feedback.

Thanks again for spotting these errors for me!

Weird! cannot convert "0.0" to length?
"0.0".to_l should always work shouldn't it? (Um.... apparently not!)

What were your model Measurement units?

Oops... U.S. decimal places. Sorry. I will fix it and repost!

Hi! Thanks! I will check all of the faces again... I need to fix a preconception I built in about decimal places (oops) and at the very least I will put a variable in the constants file that will let you add more segments to the arcs. Long term I need to add a settings page for that and smoothing...

Should be an updated post in a couple of days. if you could try it again after that, I would greatly appreciate your feedback.

Thanks, Jay

Dave R

Jay, I will be happy to try again when you post the next update. It seems like it could be a useful plugin even if you don't want to 3D print the results.

Looks really nice! I could have used this on a project about 2 years ago

How do the threads turn out on your Formlabs? Are supports required, and if so are the threads usable without post-processing?
