Parametric hook, universal and very strong.

I’ve been looking a while for a parametric hook modeling, but I didn’t found any available model that ideally combines strength and customizing possibilities. So I tried to create the model I wanted. This is an attempt for a universal and very strong parametric hook, easily 3D printable as a "finished product".

I did a "stress test" with my parametric U-Hook in its default configuration. The hook had been printed in PLA, with 2 perimeters, 0.2 mm layer height, and 20% infill.
It supported a weight of 47,4 Kg.

Full documentation available as a PDF (in English and French) in the "Thing Files" section, or on my website :

To customize this object, you can use Thingiverse's Customizer, or OpenScad software (free and open-source).

OpenScad is very easy to use if you just want to customize an existing SCAD file. I wrote a little tutorial about "how to use a parametric file", that explain how to use OpenScad to customize a parametric object :

For some reason I can't seem to see the hook true/false setting when opening in thingiverse customizer.
Or is this a feature that requires the file to be edited in openscad?

Update : Customizable U Hook is now fully compatible with Thingiverse's Customizer.
Please try it again!

I updated the file to make it fully compatible with Thingiverse's Customizer.

Anyway I still incite you to use OpenScad with scad files (parametric/customizable files).
Change values in OpenScad, press F5 to preview, when you're done press F6 to render, then go to File/Export/Export as STL, then... ready to print! There is a link in "things details" to a little tutorial I wrote about this.

Furthermore, it's also a good way to understand how this kind of files are made.

By the way, thank you everybody for all the nice comments!

I have the same problem,

Absolutely awesome! Thanks for this :)

This is great. Would these work with the 3M Command Strip product?

We wondered the same. I think it will do.


Great tool. Thanks.

I've designed a hook with clip to hold towels. You can add this clip feature to your work. I think that will make it more useful.

amazing. splendid work!!

This is the best documented Customizer I have ever seen! A++++++++++++ :)

A very impressive job, thank you very much! Great visual guide about parameters, I'm really happy with your design!

Thingiverse says this will fix all my hooking problems... :)

As said by others...great documentation.

Easily one of the most requested and useful Things around.

I am so impressed with this documentation!!! You've made the customizing process easy. I usually have to fiddle with values until I figure out what each setting does. Good job and thanks for being thorough.

Nice documentation!
