I spent a few days and printed some test parts to fit into the standard 72mm x 70mm fence extrusion. Did the final iteration today and it’s ready to go. I changed it to use a standard 90? cone point set screw (I machined a couple to 60? point here because that’s what I had on hand, but they aren’t readily available). I designed this with the threads in the model, so it prints the threads into the part, but most likely you will have to chase it with a 5/16-18 bottoming tap to clean up the threads. Mine seems to print the lower portion of the threads just fine, but the first turn or two is tight.
This design allows you to slide the tongue into the extrusion and just snug the set screw which wedges it into place, comes right back out with loosening the set screw. I don’t really want to get into the printing of these, so I’ve uploaded the file into the files section.?
A couple of notes, I set my slicer to do 1.8mm walls and then did 3mm top layer. The extra wall thickness makes it strong enough to use the screw to wedge it tight, and the extra thickness at the top will allow you to trim it to exactly the blade position and (hopefully) not go through into the internal support structure. I just did these in PLA as it prints fine and seems plenty strong. The “tongue” sticks out 1.625, so hopefully that’s pretty close to what most of the machines measure from the blade to the rip fence extrusion. Print it oriented with the face in the first picture down, hardest part is getting the damn support structure off the bottom once it’s done.
Oh, set screw is here:? ?
Backside, hard to see, but it has four splits to allow it to wedge open
Slides right into the fence extrusion
Tighten the set screw and it locks it in place

Hopefully tan and? taupe!?

You can print it in any color of filament you can buy…?

No… don’t really want to get into selling 3D printed parts. There are plenty of online or local people that will print for you, just provide the file I uploaded and that should work. You can go to Shapeways for example (pricey but I have used them in the past and the quality was good) and they can print for about $80 each.
Someone local should be able to print them for a lot less… look on Craig’s List of Facebook Market place for somebody close to you.

Brian, you may want to make this in 45 degrees as well …  For those making their own from UHMW (as I did), this is the cut …  The fitting for my Hammer uses a threaded UHMW insert …  Regards from Perth Derek

I wouldn’t know where the 45? cut lands, and how consistent that is from machine to machine. I would probably think that might have to be a machine to machine custom situation. Honestly I don’t know that I’d worry about it at angles on the leading edge, just back up the trailing edge to stop splintering.

Hi David,
Thanks for thinking of me but the aquamarine PF wheels are on pre xroll KF700.

The STL is awesome! Can’t wait to use it!

Not sure I would want the graphic representation of missing fingers after you trim that to length… :-)

What plastic type do you recommend printing it in?
|
I printed in PLA as it’s what I have and I don’t see it being an issue. You could do PETG, Nylon and carbon fiber filled, but I don’t see any advantage to any of those. I have a LED light mount I printed for my CNC mill about 3 or 4 years ago, it’s still working despite being sprayed with coolant and covered in chips all the time, just used PLA on it as well.
