Hi there – have been watching a couple of videos to try and achieve what should ultimately be a printable candle holder, but am having some trouble with the end mesh. The script is created using a ‘faceted dome’ and then in order to get the appropriate offsets for thickness, using Weaverbird ‘Mesh …

I think this can be a lot simpler! Here’s a definition that makes a solid closed planar faced Brep, for which the default meshing is watertight, and without any plugins/subdivision/remeshing. You choose a face to open and it orients it so the opposite face lies on the ground plane (and also makes …

Hi, I don’t have weaverbird but when ahead and flattened your lofts before joining and baking the mesh, from there i turned it into a SubD and did an offset. See attached. You can do some further refinement as needed to the subD. Figuring this route might get you closer. [image] ReMeshyIssues.3…

I loaded your GH file and exported the final mesh as an STL file. The latest version of PrusaSlicer loaded the STL file with no errors and sliced it fine. My default is mm so I scaled your file up 300% before slicing. [Screenshot_1] I see no problem printing this, but…you’ll have to orient it so …

My apologies, i didn’t realize i was working in decimal feet, so the models above are large. This is brep to quadmesh [image]

If you are getting an STL into the slicer software and it is not throwing errors when generating G-Code then the spaghetti may well be caused by a print setting or printer error. Classic spaghetti causes include prints not adhering to the printer bed or prints cooling unevenly and curling up at the…

Thank you for checking this, @Birk_Binnard – yes, I too wasn’t getting any errors on the slice and I had re-oriented it to be planar after baking, so that wasn’t a problem. Basically, on starting the print, it would do the raft and then begin the first layer and kind of stop extruding, then as it …

Hi @Japhy – appreciate you looking into this too. Will try a couple of your solutions. Any thoughts on the removal of some of the top surfaces in order to create that opening I mentioned in OP? Ideally, this would follow along with the randomness of the facets / seed generation – just not sure how…

See attached for a script that cycles through the various facets once oriented to the XY plane. Once you find the one you like you can plug into your definition. [image] Re_Polyhedra.gh (19.8 KB)

This might be a little hacky but could work in this case. Requires elefront. Once you’ve chosen the configuration but want to edit the shape slightly you could bake the curves and move the points around a bit (F10 turns on control points) These are re-referenced and should work OK in your definiti…

A nice thing about this method is that (presumably) you could print each face separately, face down on the print bed, and glue them together afterwards to avoid the need for support structure and to get a consistent finish on each face.

here is one using an offset Brep component from the Sasquatch plugin, there’s one in parakeet too i believe.
