If you read my last post on modular components, you may now be thirsty for more information on insert nut installation.
I have read many articles and have been testing a few parts and insert nuts at the Makerspace. I am still working on the ideal settings and parts.
I have found these articles and videos very useful:
A very good video from CNC Kitchen, as he explains different types of insert nuts and then tests them: https://www.youtube.com/watch?v=G-UF4tv3Hvc&feature=youtu.be
A good article on inserts and useful specs at Hackaday: https://hackaday.com/2019/02/28/threading-3d-printed-parts-how-to-use-heat-set-inserts/
