This thread is very old, however I just got the dreaded "model is not watertight" in the latest Cura. I did two things (I know, should have done one at a time to be sure which solved it). 1. I opened my Blender project and changed the measurement units from Imperial to Metric. 2. Selected the object and opened Object Data Properties. Chose Remesh, left the defaults of Voxel mode, size = .1 m, Adaptivity = 0 m, Fix Poles is checked and Preserve volume is checked. Clicke on Voxel Remesh beneath those fields. I saved the project then exported my stl. It now opened without warnings in Cura.
