I wanted clamping dogs that I could use with the stock Festool MFT fence and not use the miter gauge. This design fits with no slop in the MFT holes for precise alignment. In addition to the print for each clamp you need 2 M6x25mm hex bolts and nuts, you'll want a pair of these. One bolt goes down from the top into the nut in the lower knob. The head of the other bolt engages the track in the fence and the nut goes into the tightening arm in the back - if you screw the bolt in the right amount the level will lock and unlock the track with about a 90 degree turn. (2/25/2018) I've added an alternate bottom knob design which is bigger and easier to grab by hand. It can be used instead of the other bottom.
I've also now added a third knob design. For some cases the big rounded knob felt great, but was too big. I found the 8 ridged knob designs to be a bit rough on the hands if you really needed to grip them. So now I've added a 4 ridge knob design which should let your fingers get in there to grip them, but are still small enough to not cause clearance issues. I'll leave the original 8 ridge design here, but I'd suggest one of the other two.
Printed in PLA. I used a high infill to make this part effectively solid for maximum strength.
