I insert mine with a soldering iron at 150c something, I get it in 90% of the way then finish it off with a flat metal object so it sits flush to the surface, I finished printing the parts yesterday and I sanded and painted them. I'll attach an image of the inserts well... inserted.

Hi all, I've been excited to do this project and I am familiar with CAD, so I have made some modifications to the original design to use threaded inserts, I haven't tested the design yet, but it is meant to use M2xOD3.2xH2.5 threaded inserts and M2x8 screws. Find all CAD files and OBJ files...
