By coincidence this would have been my approach, the good old trusted "jig saw tenon.
It worked well when 3D printing that odd shaped box recently.
I am not proficient with Fusion but it is installed on my computer, so I can give it a go, thanks for the "how to" do it info.
My printer bed is 255 mm x 255 mm, so? I think I could print the tyre in 3 pieces and join together, maybe the 2 sets of tyres needed in one hit.
I can always print 1 piece again to a different length if I find my total circumference dimensions are wrong when assembling.?
Cheers
