wow, web app was really impressive, thanks for digging it up from the internet fossil record.
For reference, this is that project blog post link: TubeNotcher Paper Template Generator | Devpost
I think this is all possible to do with the free version. But I feel like the amount of friction for a garage builder would be too much…
At best, I am a mediocre software engineer, but I think I can hack a basic tube notcher program in python in a week. I will give it a shot when I have some time.
oh yes, now we’re talkin’ !!! 
Mark, Sorry to be thick over here - not tryna be - but how does this script thing on Metal Geek run / get an output? I can input values… then what?! LOL
Use it on a PC or laptop, not on a phone. Input the dimensions of the tubing and the angle, and it outputs a PDF of the paper template, print that out at 100% and cut it out and tape it around the tube. Here’s an example:
tube-notcher-file tapered head tube.pdf (65.6 KB)
Interestingly enough, I have the same issue. I tried Chrome and Edge browsers.
@markbeaver is there a button to click? Or does the PDF just try to download automatically?
Well, that is interesting. I last used it a month ago in February and it worked fine, tried it just now and, yes, the “calculate” button seems to have vaporized. Hmmm.
ditto, trying on a PC in Chrome and there was nothing, BUT just tried Edge and got this @Daniel_Y
…and it’s on the Wayback Machine: Tube Coping Calculator
I am also working on it. I can use Python as well, haven’t decided what it will be but definitely web based, maybe web assembly.
Found this: Tube Joint Pattern Generator
It seems to be pretty neat, you can set multiple tubes and get the print for each, the GL panel visualizes the tubes too…
I think it could use some fine tuning specifically for frame building
Hey, ya, Andrew from BFS sent me the link to that one. It is a bit complicated but it seems to get close. The printouts are really hard to make paper template from tho IMO. I am trying it today…
I think my lesson here is I just need a mill and a miter daddy! 
The Dogfeather app is still available and working over at Web Archive. Perhaps the code could be scraped and packaged up.

All the best,
Sometimes, I use the sheet metal feature in SolidEdge to create a paper template. It is not hard to do. I guess solidworks and fusion360 can do the same.
Thanks so much! I didn’t even know such an archive existed.
I should look for Yamaguchi’s website there, too, ha!
AH!
The website is: dogfeatherdesign.com !!! That’s why I wasn’t able to find it! Thank you, it will be useful
Alright, the quickest thing I was able to do is to duplicate dogfeatherdesign.com and I am now able to run it from disk without issues (took some time to remove all the waybackmachine artifacts).
I am thinking of two solutions to deliver it:
My main issue with #2 is that this is not my code, not sure how the owner of the original website would feel about me posting his work without his permission. Thoughts?
For whoever wants to try it out, unzip the file and open the index.html with your browser of choice.
Looks like it works! Wow, incredible skills. Don’t know how you guys do all this stuff!
If anyone know the owner and put me in contact with him, I could put this online as opensource (and free to use) but I kind of need his permission…
I had heard that the person who was Dog feather design passed away.
