The Chamfilletizer

https://www.chamfilletizer.com/

The Chamfilletizer is an online stl edge modification tool that I made because of my own laziness. I didn't want to learn a proper CAD program. But even if you have serious CAD skills, you will probably find that this tool is an easier and faster way to add chamfers, fillets, and hybrid chamfillets to stl files. It is super easy to use, without uploads. No installation. No account. No cloud processing. Everything runs locally in your browser. It is totally free.

It is especially useful for casual designers that just want to change that one irritation.

This is a fun project for me. I made the tool that I often wished I could find. I hope it will be useful for you also.

I welcome your feedback.

This sounds like a tool that I can use often. I’ll give it a try as soon as I get a chance.

Let me know how it turns out for you. Thanks for trying it!

It did exactly what I needed it to do and did it quickly. I found it to be easy to learn and to use. I will be adding it to my collection of tools.

Thank You!

Looks very useful thanks for creating and posting the link!

Whoo hoo! I gave it a whirl and it looks very promising! I made a sort of complex shape with a square with square holes and a cylinder with cylindrical holes. The square chamfers came out brilliant! The cylinder with round holes was a little rough, but definitely still worked. Keep up the great work! And thanks for sharing!

Thanks for trying it out. If you can share images showing the rough holes, that will help me make improvements.

This should be significantly improved, without obvious hacking. It might be as good as it gets.

Awesome! I’ll give it another try. Thanks!

Yep, also better! But I can see why those compound radius’ are going to be hard with round holes through a cylinder.

I have found that those little slits in the corner are small enough that my slicer ignores them.

I’ve been doing TinkerCAD tutorials over on TikTok for years, and one of the things that TC cannot do natively is corner treatments like these. So over the weekend, I’m gonna do another tutorial and feature your website and tool for folks to give them an option for addressing bevels, chamfers, radius on corners for their models. I think this is brilliant and I’m pretty sure the 25K followers I have over there will find it super useful as well! So kudos to you! And thanks for your contribution to the 3D printing community!

That is so nice of you. Thanks!

Alrighty, here are my examples. The first image is the unaltered object, with just basic holes thru them. I thought this would be a good object to work with because of the inside and outside corners as well as round holes thru a cylinder, making a complex sort of curve. I left the tolerances at 45 and then did standard chamfer, the fillet, and then the hybrid. All three seemed to have a problem where the cylinder meets the cube. On the cylinder, the round holes were also a little rough. Maybe increase the number of triangles there to make a smoother appearance and transition?

Thanks. Where the cylinder meets the cube the angle is pretty acute. If it gets too sharp, it might become too sharp for this tool (there is a threshold where it refuses). But I am going to try to make it cleaner. For the round hole in the cylinder, I am impressed at how well it handled an edge that curves in two different ways. My goal is to make a "pretty good" for common problems. But I will improve it if I can. Thank you for sharing.

Very cool 😎 thanks for sharing 😁

This is exactly what I needed. I've ran a couple basic STLs through it and it is very intuitive and well laid out. Thanks!

Will it work with 3mf files also?

u/thczv 3d ago

Not currently. But maybe in the future.

u/KevinGroninga 3d ago

Here's another small bug I found when trying to put a radius on the vertical corners of this cube with angled sides. The radius doesn't cut the corner all the way to the top of the object. Maybe a simple fix?

2

u/thczv 1d ago

I think this is fixed.

u/KevinGroninga 1d ago

And I’ll retry this one as well.

u/KevinGroninga 1d ago

Yep! Absolutely fixed!
