Create your design with holes or pre-drill holes for where the insert is going to be placed. These holes need to be a little smaller than the outer diameter of the insert and about 10-15% deeper than the length of the insert so that plastic will melt, deform, and mold around the insert properly. You may need to experiment with your 3D printer as some are not very accurate and the inserts themselves can have different outer diameters even if they are the same thread size.

The hotter the iron, the faster the melt will happen. This may be desirable in a production environment. If you are a beginner, set the temperature right at the melting temperature of the plastic youre using or the extrusion temperature of your 3D printer. ABS - between 490 and 700 F (255-371C) PLA - 356F to 428F (180 - 220 C) If the plastic begins to smoke, lower the temperature. If no melt happens or too much pressure is required, raise temperature. Even plastics within the same type may have slightly different melting properties and you may have to experiment a bit.
