That’s brilliant! Whenever I design something with mating parts, I generally end up reprinting just the joint over and over, tweaking it ‘til it’s right. The article describes how the original intent is to compensate for the cant required to get the part out of inject molds. In fact a similar thing happens in 3D printing, where layers close to the print bed tend to ooze together, while upper layers to not, leaving a conical hole. This technique will solve all that.
