Question about threads and 3d printing

3d printed adapter...designed in FreeCAD of course

For accurate and perpendicular insertion using a cheap soldering iron.

Good idea, thanks for sharing. Could be further improved by an adapter to the soldering iron assuring that the insert is properly aligned to the soldering iron. E.g. by a tangent constraint .

I made tips for the iron for each size insert so the inserts self align on the end on the soldering iron

heat set brass inserts are definitely better than printing or tapping threads. IMO

No doubt, but as always, "it depends". For a simple one-time, low-force assembly a tapped hole would be fine. For repeated use or higher strength the insert rules.
