I am newer than a newbie to 3D printing. I have asked this question before but still having a problem with Cura telling me my model(s) are not watertight. I have attempted to use what was previously told to me with no sucess. Yes. I have normal windows in my models but what models don't. I tried downloading a model from the internet from a respected designer but got the same 'watertight' error. Any suggestions from anyone. PLEASE

Thank you for all your suggestion/recommendations. I will follow each one and see if any wotk. Thanks again.

Once I load a file into Cura but before I run the file through the slicer I get a message that says "model is not wateright and may not print properly. This is not my original model but one I down loaded from Cults 3D so I can't change it. Anyone have any idea on what I can do to get the model to print?

Yes the memory card is new. I got the card when I purchased the printer. The error appears in Cura after I am done slicing the file and I want to transfer the file to the flash drive. Many thanks for you attempt to help me. I am not even close to being a newbie so any help you can give me will be greatly appreciated.

Hello, I recently downloaded Cura software and sliced my print project. When I went to load the G-code file to the removable disc in my computer I got the error message "There are no file formats to write with". Can someone please explain, in detail, as to what I need to do to fix this situation? Thank you in advance
