Different services show different results

Hi there,

I have made my first small little object and would like to let it be 3D printed.

The company I want “work” with has an in-built application that fixes some bugs. I thought I already fixed all of them but it seems that I didn’t.

I downloaded their version and uploaded it to several online services. Now I don’t know if it really looks the way I want it to look because depending on the online service, the file either looks perfectly fine or is a bit messed up…

How do I make sure that the print will look fine?

How do expect us to answer this since you feel fit to not post model. You can not make sure but do the best you can and go from there. Suggest you modify your model to suite what you want and have them recheck and go from there. Just make sure you use one of the well known commercial printers.
