To facilitate inserting heat inserts straight (or at a given angle), this adapts a Dremel Drill Press to carry a Hakko soldering iron. Should be quite tolerant of print settings, but I suggest using PETG, 0.20mm Quality, 3 perimeters, and variable layer height. Installation is fairly straightforward - be sure to hold the drill press lever in position when replacing the stock adapter, to maintain spring tension. The iron needs to be pushed into the holder firmly, then the clip can be installed (right side up) at the top. Version 3 adds a spine to prevent flexing in the Y-axis.
