flower ring ready.3dm (12.2 MB)
I need help boolean unioning this ring because im having trouble 3d printing it as the slicing software fills the gaps instead of keeping them open. Its for a university project due soon if anyone could help i would appreciate
The small rings in the flower centers are open meshes. You’ll have to close them before the union operation will work.
@Joshua_MacGregor I reduced the mesh because otherwise I couldn’t upload the file, but you can use the same procedure if you want a more detailed mesh.

I think the poster is on Rhino 7? Shrinkwrap will not be there.
if you want to get into detail on mesh repair- check out this video.
in your piece, the rings in the center of the flower need to be closed up. Using patchsingleface on a few sections then using fillmeshholes will get you there.
see below
now… heres the magic trick for pre v8/shrinkwrap parts for printing.
don’t boolean them.
leave them as watertight parts that are over lapping, export it as one stl (verify that all normals are pointing outwards) and let the printer slicer combine them for you at print time.
but… if you do a lot of this type of work, an upgrade to a version of Rhino that has shrinkwrap is going to be a game changer for you.
@Joshua_MacGregor
your data is messy and as @brvdln wrote shrinkwrap will be the fastest solution.
If you want to solve the issue by mesh editing it will become very laborious.
there are a few issues:
those flat-overlapping meshes will cause trouble.
Also notify that Meshbooleans got rewritten in rhino 8 (your file is rhino 7)
at least fix this flower-leaves with shrinkwrap:
remodel the inner flower-revolve-detail - it s a simple revolve … much faster then mesh-editing:
now rhino 8 can mesh boolean it:
also something is strange on the basis / main ring: (even if rhino states closed mesh)
in front you the ring looks a bit skewed:
after above fix rhino 8 is able to boolean union with a coffee break:
my recommendation:
remodel the inner flower-revolve-detail to make it solid / closed - and check if your slicer accepts multiple closed meshes (and combines them layer-by-layer) - most modern slicers do this.
for the next project - rethink your modelling-approach earlier
hope this helps - happy modelling / kind regards - tom
fixed file 177Mb via wetransfer … but not the original design (9 times the same flower with arraypolar) … only fixed one side of the basis-ring
