I think they're all essentially very similar. The major difference between the original Mini Kossel and the others is the use of 1515 extrusions, rather 2020. The Cherry Pi (and I think the Griffin too) use magnetic rod ends, rather than ball joints. I've never used magnetic joints, but I like how simple Traxxas rod ends are.
That said, you can find vertexes for a 2020 Kossel on Thingiverse, and I've actually just completed modifying and printing the vertexes for my own Kossel 2020 build (soon to be on Thingiverse once I complete the carriages to match). I'm using T-Slot extrusions, and it differs from others by mounting the extrusions at a 45 degree rotation, so that V-Wheels can ride on the corners of the extrusion, just like the Kossel Clear...
Depending on the scale you're going for, I'd say go for 2020 extrusion. It's often a similar price to 1515, and it probably makes for a much more rigid frame (bigger vertexes, more surface area contact with the vertex). Whichever design you go for, they're all good, and you'll find that a lot of parts are interchangeable.

Thanks for the replies,
I really like the Cherry Pi III and the support around it too, I think I need to sit down and read every page of the cherry pi thread, I am a bit confused by the different variants of the parts (magnetic/non-magnetic, some pictures show the arms with and without wire and springs attached), I don't know why but im not keen on magnetic parts on a printer, I can just imagine it coming apart. I would like to make the non magnetic version using something like an E3D head and incorporate auto levelling (not sure where the STL files are for that).
I will ask any further questions in the cherry pi thread.
Thanks

I think my question matches the thread so i just use it for my specific question in choosing a delta design:
I am also thinking about building a delta and the bigger slice of cherry pi sounded interesting to me. But i want to have a really heigh build volume of about 80cm.
So i was thinking to go with 30mm bosch-rexroth extrusions. I couldn't find any v-rollers for them? Has anybody experience with that? Is it worthwhile to go with even
bigger extrusions?

Yes the parts if scaled correctly will work with 30x30 but how about goint with the 20x40 stuff (Add additional bracing if required) then the std parts will work

I myself am going to add some 20x40 extrusion vertical connected to the cross pieces and then enclose the whole thing in Ally sheet which should stiffen everything up

The open build V Wheels fit 8mm slot too.

Do you think that the v-wheels work on bosch rexroth extrusions too?
Best regards
Tim
Edit: I was confused due to the V-Slot extrusions at the openbuildspartstore. As far as i see the bigger slice uses rexroth extrusions so it should work.
