Tap holes on the 3D printed components
Dear guys, for the 3D printed AR3, how do you tap holes? For those structural components, is there a summary page that specify which hole need to be threaded with which tap size?
Sometimes I already assembled a part and then realized a hole is not tapped on it. It will be nice to have a summary of all the tap specs. Thanks!

I would tap each hole according to the screw called for in the directions, I apologize that I didnt include that in the BOM or summary. I would clear the hole with the appropriate size drill first and then just use a hand tap. for a 3mm screw I use a 2.5mm drill and for a 4mm screw I use a 3.3mm drill.
