Is this webshop also yours? https://www.plastskiver.dk/#!/products/mft-bench-dogs-clamps-til-festool-mft-bord

Or someone is selling your design as his design.

The guy was totally in denial.
Finally, he did a search and "found an item very similar" to his design "on google" and decided to remove it from his shop.
The Thingiverse of mysterious ways...

Hi Martin,
Thank you very much for your message, this is the third time...
This violates the Open Source license by many ways, as I wanted it to be a non commercial license.
I particularly appreciate the rebranded action with copyright !
There's too many dishonest people on earth !
I write to him immediately.
Thanks again, take care ;)

Thank you for this great working tool!


These work amazingly well. I would like to scale some of part to be higher (taller?) (I use them as benchdogs for a DIY Festool style table). Any chance you could share your original files, or some other editable format?


Sorry Pandionx, I don't have the software I created this stuff on any more.
This is pretty easy to recreate with the provided plans.
You can scale it up on your slicer too.

Love the design and the model. They print so perfect. Now need to find a 20 mm PVC somewhere in Home Depot or Lowes :)

Hi Ali,

Thanks for your feedback !
If you can't find 20mm tubing, there's a model fully printable.
With Polycarbonate filament it should be pretty strong for medium duty purpose.

I got the mdf along with 20 mm bit, drilled holes using your amazing jig, printed bunch of clamps, a bit disappointetd that none of the printed item fit (excpet the half one with the jig). Now I have one broken one in the cnc bed.

I am printing this now!
Great design!

Is the 96mm spacing from the center of the dog hole, or the edge?

Thanks in advance.

Hi Scott, The Festool system is 96mm center distance.

Does this need 96mm dog hole spacing or might it work with 100mm?

Oh, and what are the little triangles on the bottom of the parts for?

Hi Ian, It is meant to be perfect with 96mm spaced holes, that means you can even clamp a piece of paper...
It should works fine with 100mm grid as long as you clamp parts over 4mm thick ;)

No, you can end up being 4mm (per set of holes spanned) short of being able to clamp items. However, my router bit fell out of my collett half way through anyway, so the job needs redoing, and will be redone at 96mm.

OK, triangles end up on top and I guess are alignment marks.

Hi again Ian.
True, that shows the 3 different contact faces.
Enjoy !

Very cool! I’m having trouble finding the .pdf file for these clamps so I can print and make them.

Thanks in advance!


Hi John,

Thanks for your comment.

You can find the PDF file under the tab "Thing Files" just above the new post field.
It's called "FestoolMFT_DIY_Clamping_System.pdf"

Enjoy !

So there is only 1 .pdf in the files? The dims are only on the openings...Not sure how to make the different cam blocks...etc.


I think I will try this, seems like a really good idea!

What is the difference of the "lightduty" version? It seems you would not need the 20mm pipe in this one?

Thank you !
I just adapted the Youtuber Marius Honrberger's idea to the Festool's MFT system, with few improvements.

great guide, my only concern, is 20mm pvc pipe? I printed these and went to my local hardware bought some 20mm pvc pipe... doesn't fit. 20mm pvc pipe is measured internally not externally, no one in Australia sells 20mm external measuring pvc pipe...

Salut. Bon design. Je travaille aussi sur divers accessoires festool a imprimer. On pourra peut etre partager nos idees a l'occasion.

Merci ! Oui, pourquoi pas ?

would you be willing to share your drawing files? I would like to use CNC to make these clamps.

Unfortunately, my software cannot export CNC contours only. Anyways, PDF plans are available here. You can import and convert it to DXF files in any vector software (Illustrator, Inkscape). Vectric applications will work too.

Thanks for the info.

i really enjoy the idea i ll make one as soon as i i can
less trust in the mft hole jig
but i relly like your clamping systeme

Thank you, your comment is greatly appreciated.

I understand you may be not confident with the drilling jig.
Sometimes you don't know why you prefer a tool instead of another.
Actually, I drilled 3 MFT tops with it, various sizes. Both was pretty accurate.
I noticed no deviation on the biggest one (1450mm). The jig is still in good shape.
You only need to be right for the first two holes. Then you can't fail.

ok may be i ll make a try
thanks for sharing your ideas and your work

You're welcome mate ;)
