I needed a rod eye for lego, I make rod eye for lego.
printed at 0.08mm layers, put the parts in boiling water to make them soft (pla) and push a lego axis through them. I printed mine with supports and in one piece. the 0.3mm released but it took some wiggling and hot water. But I could calibrate my printer better as well.
The 0.6mm has a lot of play in it.
