Printing fine details without the tool crossing the part? (self.3dprinting)

I'm trying to print a small 1-walled part with fine details. If I just model and print it in PrusaSlicer, the travel moves cross through the middle of the part and leave strings. "Avoid crossing perimeters" does not help:

I'm playing with a really hacky solution, where I model the desired tool path in vase mode, and post-process the gcode to disable extrusion for straight walls at particular angles in the x-y plane. Here is the result:

This is effectively "vase mode with gaps" but my implementation is hideous. Does anyone know of a better way to prevent travel moves from crossing the part? Perhaps a different slicer or settings?

Edit: Here's a link to the STL: https://www.thingiverse.com/thing:6948297

@p1mrx you could try making the seam in the middle of the part. It won't cross but will still have to travel. Vase mode would work if it was two wide!
