I have made a small corner with M8 threads in it.
When I export it as STL and upload it to shapeways, I can’t get the holes to be visible. Where the holes is the preview only shows solid surface. But when I upload without threads it shows as it should. Now I can’t figure out what I’m doing wrong and I would be very glad if someone could help me. I have also verified it in Meshlab that it opens and looks ok. But I’m not really familiar with Meshlab yet so… I have run Cleanup on it before export to STL but it’s the same issue.
Attaching both STL and SKP. Btw, when modelling I scaled up first 10x and scaled down. CornerM8.skp (777.8 KB) CornerM8.stl (2.7 MB)
Your SKP is not a ‘solid’.
Run Solid-Inspector on it to see the issues [Xray mode and section-cuts help both seeing and fixing issues].
There are several internal [sur]faces
You need to remove the problem geometry…
You also have some ‘tiny’ issues, try temporarily scaling up x100.
Solid-Inspector will highlight the problem areas for you, although it can’t fix them…
After it reports as a ‘solid’ in Entity Info, the STL should export and print OK…
Oh, that was very nice. How did you clean up the model so fast? I would really appreciate if you could take time and explain that so I learn something new for the future.
I must say I’m really impressed how many talented people it’s here that make time for writing and aiding newbies in need! Thanks!
