Can anyone tell me what’s going on with this stl and how I can repair it?
Clearly it seems that the original stl consists of overlapping objects and cura interprets the overlap areas as empty rather than filled.
I tried doing a repair in Netfabb, I also tried importing and re-exporting out of various programs including blender,Openscad & Autocad. I couldn’t solve this- granted I am a complete novice with Blender & Netfabb.
I now have the engineering drawing for this and I can redraw it in a fraction of the time I’ve spent fiddling with STLs but I want to learn something from the effort I’ve already spent on this.
The attachments are largely self explanatory but you can see how cura shows in in normal view (what the customer wants),
how it printed;
and how it shows in blender
Thanks in advance to anyone who has any ideas how to resolve this given just the STL
