I really liked using heat set inserts but it was a bit of a learning curve to design for. I've used m2.5 to m4 and would definitely recommend going for bigger screw sizes if your part can allow it. I've had issues with plastic getting into the small sizes and semi ruining the threads
I got m3 (still using first batch of 50) and had 0 problems. I made 4x4 mm square hole (since I was printing it on the vertical wall) and it was perfect fit. After that I tried 3.8, 3.9, 4.1 and they all seem good. Insert outer diam is 4.6 mm and holes are always bit smaller when I print them like that. Maybe its also about the shape of insert or soldering iron tip, or Im just lucky hehe
