Hi, I'm trying to get this to slice in cura 5.6.0

Yellow block is set as a cutting mesh. Can Cura just not ignore stuff outside of the bulid area?

iso top bottom

I'm open to suggestions on how to cut it outside of cura as well. I tried meshmixer, but the import absolutely destroys the stl stl iso

Thanks!

I don't think that Cura is smart enough to cut STL files apart like that. My guess is that a program like blender would be best to do this, make a shape the size of your printer's build volume (or slightly smaller), put the part you want to print inside of the shape, then remove everything else.

I'm not familiar with blender but that's the work flow I would approach with.

Here’s how I would do this in blender:

  1. Import the stl
  2. edit the default cube so it overlaps the part of the stl you want to delete
  3. add a “boolean” modifier to the stl that is set to “subtract” the cube
  4. apply modifier
  5. export as stl

Can even use cylinders to group some circular parts of the model together naturally so that the “glue” points are at the bottom inside the walls where they’re not obvious

@WolfLink @papalonian yeah, something like this but you might try. MS 3D Builder is out is still around our even good old Meshmixer!

Alternatively you could try adding a plane and extrusion this downwards on blender, Meshmixer etc
