Great design. Printed it over night on Prusa MK3S and works very well. I would love to see some modification for female part to be fixed to MOLLE webbing. Something like this: https://www.511tactical.com/rush-tier-system

Really good design and worked first go!!!

Elegant Design and a real improvement over a traditional clip, both in function and in ease of printing.

Super Objet, il es dommage cependant de ne pas fournir les Fichier Originaux pour permettre l'amélioration

dans mon cas j'aimerais apporté une modification la dixation des sangle, car sa glisse

Prints well and works great, even when scaled to smaller sizes.
Very elegant design!

PRINTING TIP!: reduce the size of the male fixture by about 5%. I printed the toothed set, and the locking mechanism works well however it takes extreme force to get the male fixture in deep enough to latch. im just hoping it will become easier with time and sanding.

also the webbing holes are very roomy and don't grab thin webbing well.

good design though.

It prints well on my printer with the default sizes but I'm glad you got it working for your application. You're right about thin webbing. I had to accommodate thicker webbing and I just double it back for thin.

Hi, could you share me .STP files? It will be handfull for me ! Thanks

I feel dumb asking this question, but is there a guide on how to connect a strap to these and make it adjustable?

You feed the strap through the slot closest to the buckle from underneath, then over and down the outer slot. It should hold depending on the strap thickness. You might need a strap keeper to hold the strap from slipping under a lot of force. I'll also upload some keepers here.

Do you maby have the design files? Id like to edit them so I can use them for paracord bracelets.

Дорогой друг, мне очень понравилась ваша модель застежки, хочу использовать для ошейника моей собаки. не могли бы вы изменить немного модель для этого, убрать одну проушину для ремня. или если вам удобно поделитесь файлом редактируемой модели.большое спасибо.

For some reason Simplify3D refuses to slice either of the female buckles. It just gets stuck on generating infill, and never proceeds. I have to shut down the program and relaunch in order to be able to do anything. Everything else slices fine. Could there be something wrong with this model?

EDIT: Interesting... I changed from 0.2mm layer height to 0.25, and it worked...

That's odd because I printed it using Simplify3D. I print with 4 shells, nozzle 0.4mm, 0.2mm layer height.

The teeth didn't print very well. I think they were too small and pointy. I joined them in groups of two and re-uploaded new models. Take a look. I think they'll print better. Might want to just print the male side first to see how it prints.

Do they work or are the teeth too fine?

I would like to add some teeth to where the strap goes to give it some more grip. It slips on the strap.

I've been meaning to do that actually. I just added them and uploaded the new models. Let me know what you think.

Very nice. I am printing now. Thanks

Please post a "make" if you can when it's finished. I can't print it right now as I have an 8 hour print going for an unrelated project.


A fantastic design I just used the small on one a 5-mile ruck and it never came loose. Would it be possible to get the cad file? I just bought a used backpack that is missing all of the buckles, I need to scale up and down. I am using Autodesk Inventor and Fusion 360

Im so glad you liked it. It's great to hear that it's holding up for you. I've been using a few for months and no failures.

I could post the file. I used Fusion 360.

You could just scale it in your slicer though. That's how I print different sizes actually.

Nice work... What material did you use? Thanks

I used PLA. It's very strong.

What material is it meant for?

I've printed both PLA, PETG, and ABS. PLA is quite strong in this application. I found no need for PETG or ABS. I'd use PETG or ABS if you planned on leaving it out in the sun and needed them in black. Otherwise, I'd just use PLA.
