Fitting parts together
This is really hard to describe. Somebody posted on the subject of fitting two printed parts together and rather than trial and error scaling, one part had tiny compressible nubs on the mating surface. Appearently a technique origination in injection moulding. Can anybody remember the name or even better a link to the thread.

I found it, it's called a crush rib.

compression ridges. I read that article and know there were some prints with the examples, but I just can't find them. Basically you loosy goosy the hole and add in 5 to 6 little lines for the length of the hole all around the inside. When you push the rod into the hole, the ridges deform - sort of forcing a fit that is hard to get apart.
RE: Fitting parts together
I think you are describing "crush ribs" for press-fit injection molded parts. I think Angus did a session on this topic in his Maker's Muse YouTube channel, but I can't locate it right now.
