Is it the model, or is it my settings?

[slayaz 2]

Hi! Thanks in advance for your help. 

 

I have downloaded a model and tried to print it, but there was a catastrophic failure which on closer inspection seems to have happened after the model is sliced. 

 

I'm not sure how to best describe it, but it looks like the walls of the inner wall once sliced aren't joined. I hope you can see from my screenshot. 

 

Thanks again for any help or suggestions, I've never modelled so felt a bit daunting when i downloaded a trial copy of Fusion 360 and opened it in that!

 

Happy printing

Possibly a bit of both. The model is invalidly defined (not watertight) but when I slice it with my default settings, it comes up fine:

 

If you could post a Cura project file (.3mf, in Cura get it ready to print then go to File > Save Project) that will include your settings so if it is your settings we can figure out where the problem is. Just in case it is the way your computer is dealing with the model I'm including a fixed version.

Thanks for your help, I really appreciate it. 

 

Here is my version with my settings, if that sheds any light.

Okay, so the answer to "is it the model or is it my settings" is: it's the model. It's hollow, in that there are paper thin walls with nothing between them (not enclosed). You can try printing it by turning on Walls > Print Thin Walls but since it's only going to print a single wall in those areas it's going to be fairly weak.

Thank you! That's really helpful.  

 

My next task is to remake correctly... *rolls sleeves up*
