Alfawise U20 ONE - Stops extruding on just one print job?!?!

[mtlred]

Hello,

I recently got a U20 One which I'm really enjoying.

All my prints have worked beautifully except one.

I printed the base for this one and it printed perfectly: https://www.thingiverse.com/thing:2493459

Except, it was the wrong size for my stone. I uploaded it to tinkercad and extended the sections I needed and exported as an stl. Threw it into cura and exported the gcode.

About half way through it stops extruding and even makes a weird noise in the area that grabs the filament. I figured it was I was printing too fast or not hot enough so printed 5 different versions at different speeds and temps...all did the same thing.

If I print anything else, it prints fine...just did an eight hour print with any issue. So what's happening to this one? The one other factor is that the print has a large footprint but is still within the guidelines of this printer.

Any help would be amazing!

I've attached my modified stl.

Thanks!
