This is for mounting a J-head to a Wade's Extruder. The J-Head in the Photo is the Mk. V-b, but Any J-head will fit because it is Parametric. It Measures 70x25x8mm, so it shouldn't get in the way of your extruder gears.


Updated: I added a filling.scad and .stl, it is for the gap between the Wade's Extruder and the Hotend. This keeps the filament from getting caught up.
The Mounting Plate now has Nut Traps so you can use M3 x 25, and not have any screw left on the other side.

Update 2:
I added another STL file with a wireholder attached to the clamp, this is for holding the wires that run from the Hotend.
I kept the STL file that doesn't have that.
I also changed the OpenSCAD file, with the wireholder added. If you don't want it, just change the "wireholder=true;" to wireholder=false;"

The STL is set up for M3 Nuts and Screws, If you want to change this, use the Variables in the .Scad File, But remember to change the thickness of the overall Plate accordingly.

nice job ;-)

Printing it out of nylon pa. That should take some heat.

This looks more appropriate for mounting a j-head with a Bowden push fitting built into it!

Perfect for my needs. Ill be printing today. Ill report back later.

Thanks for the design. I made the holes deeper because I had shorter bolts on hand. Awaiting the reprint

Nice job!, would this work with an aluminum hotend?, does it melts with the temperatura?

Mine has performed beautifully printed out in ABS with the J Head which is made out of PEEK. I am not sure about how it would perform with aluminum. The only way to find out, as I see it, is to try it. As long as it is printed in ABS, it should be able to reach about 200 C before it starts softening.

Simple and great, congrats Acarius10!! :)

Thank you!! :)

I had been running this arrangement for a long time with a part i made of wood. I recently printed a better Wades model and removed the wood part. The result is a huge reduction in ooze that i attributed to hysterisis from increased distance between hobbed bolt and hotend. The new Wades does not provide a perfectly tight grip on the PTFE though so I'd still be interested in this part if you dont see an issue with ooze.


Can you share your extruder design, please?

just the thing i wanted. thanks.

Your Welcome.

Is there any benefit to this over the groovemount adapter?

I did this because the screw holes on my Wade's didn't line up with the J-Head. I am not sure if there is any benefit or not.

Well, it looks like it should hold it more securely. J-heads are groovemount, and my groovemount is made out of wood. After a little bit my nozzle starts to get a little wobble. I'm going to try this one and see if it can hold it down a little better.

By the way, this works with the groovemount wades just fine if you flip it 'upside down' from the way you have it in the picture. That allows the top of the groovemount to protrude from the top and sit inside the extruder just fine. It is a very secure fit. Thanks again. :)

You're Welcome :)
