WIP for now, as 32 hr test print has a while to go. I am currently scaling it at y = 100mm. This may prove to be slightly undersized. Will update once I know...
The final print, filled to brim, holds 560ml, or 98.5% of a pint. Print at y =101.5mm or higher to get a full pint.

Waterproofness.
The settings should be fully waterproof - I had a layer failure caused by a print jam, which I 'solved' by heating up to that layer in boiling water and pressing down hard to close it up. This caused some bulging at the base.

Handle.
I found the handle to be too small for three fingers and low on the mug. Rather than reprint I soaked the handle in a bowl of boiling water for a few seconds, then shook off the water, and pushed my fingers through, stretching it upwards. Photos of before and after are provided. If asked, I'll update the mesh.

0.1mm layers, 3 perimeters to ensure enough overlap and adhesion for waterproofing. I hope.

There's some duplicated mesh corners in the stl that I haven't cleaned up, but they do not appear to effect the slicing.
