Hole Horizontal Expansion (Cura feature in PS?)
Before I begin, I am aware that I asked about this before and was satisfied with the answers. That said, how do you use Cura without that feature? I feel crazy because no one else is talking about it, but also praising PrusaSlicer (of which I do not have a problem with. In fact I would like to switch over to it based on thispost.).
So what do you use instead of Hole Horizontal Expansion?
Test print and calibrate.
Cheerio,

That's not helpful or answering my question.
You asked:

I test-print and calibrate.
You could try it. measure the test, calculate the error and scale the part by the inverse.

So there is no easy way to do it? No way to compensate for the natural slight shrinkage of plastic using PrusaSlicer as it is?I have to change it manually?

That *is* the easy way.
If you think about it that's also how Cura's Horizontal Expansion works, it's just disguised slightly.

Yeah that's what I meant. Cura does it automatically. What you are saying is that I have to jump between 2 programs to make sure a hole is correctly sized. See this video. It's so easy.
No need to jump between programs - you do the calibration in your design software.
That video clearly shows exactly how NOT to do it.
The influencer did exactly what I do, he test printed, measured, calculated the error and applied it to the part: so far the process is the same but then he screwed up; he calibrated in Cura.
By disassociating the printed part from the design software he broke the part and must return to the design stage (jumping between programs) and reverse the calibration on the text part. Next time he slices and prints he will have to do the double calibration again...
His design software does what (almost?) all do; when a curve is rendered to a mesh the end points of each segment are placed on the calculated line, the circumference in this case, and the straight line between forms a chord. The slicer follows the chord which is sliced as the centreline of the extrusion therefore the concaves are always going to be printed smaller and convexes will nudge half an extrusion width oversize at the mesh endpoints and may be undersized in the chords. All this is basic 3D design. Any part that needs accuracy must make allowances for this. Precisely the same issue arises with all linear shaping tools, laser-cutters for eg. Incorporate calibration allowances in the design so the process become one of just changing a parameter or two.
Cheerio,
