I'm running a Mk3S with a skelestruder and unfortunately the purge mechanism is not compatible with it; the activation might work OK but the bottom of the mechanism hits the Z motor mount before the nozzle is close enough to the bed. Doesn't look like there's much room for changes to the mechanism so a revised z-mount might be required.

Do you have a 3D model of the assembly? It might be easy enough to adjust the z height of the purge mechanism as long as the nozzle is not more forward or back compared to the standard i3.

I believe there is a STEP zip in the Thingiverse files, at the very bottom.
Y position should be the same, I believe it's inline with R4 parts/Mk3S

Sorry, I meant do you have a 3D model of your skelestuder setup? Or is it just the z height of the RPM that must be adjusted? If so, How much does it need to be moved up?

Looks like it may just be the height. I'll do some experiments this weekend and report back what I find.

Update: It is not; there are other interferences with the PINDA and fan shroud that will need to be taken into account. I'll follow up with a CAD model of the assembly.

Here's an F360 skelestruder model. Motor mounts to the blue part with the ridges, I just don't have a NEMA17 reference file on hand.

Is it possible for you to export the file in STEP format? We use Autodesk Inventor for all our modelling and it cannot open the Fusion 360 format.

I can do that tonight; but for faster turnaround there is a non-assembled zip of STEP components available here:

Assembly instructions here (took me ~30 min to assemble the parts in F360 previously).

Let me know if you need me to re-export the partial assembly tonight; or if you have any questions.

Oh, and as noted in my other post - if I can get this mechanism working on my setup I'm more than happy to update and share my purge bucket post-processing script for PrusaSlicer. 🙂

Yes if you could please send the partial assembly as a step file that would be very helpful. Thank you for the photos too.

Have you had a chance to review this?

Not yet sorry. I will try and get to it this week 🙂
