Hello I’m trying to make a “flow cell” object for a 3D printer but using a series of successive boolean difference operations.
Ie substracting cylinders, etc from a block to build up a flow.
I am having a problem then once I have substracted and applied a single successful operation, further operations fail.
In the attached file I have subtracted a screw thread from a box and I now want to subtract a cylinder that is the same diameter as the tube that goes through the screw.
The operations fails and doesn’t allow me to do it.
I have tried, removing double, selecting non manifold vertices (0) converting to tris and quads but still I don’t think it will allow the operation because some of the faces of the subtraction are parrallel and co incident.
Is there a simple solution to this?
