Got all my parts finally. Just now starting assembly I went to add the 3D printed plug grips to my connectors. One had shrink wrap around it which was odd. I cut it off so that it would fit in the grip. Still wouldn’t fit. Took me a bit to notice that the base of the plug isn’t full seated into the top. Assembly wasn’t clean then it was covered with shrink tube.
Any tips on how to seat this thing fully without breaking it? Pushing by hand isn’t working.
