Ok, makes sense. Kinda what I thought, tried to fit sockets but they’re too thick. I ground down a special scubapro socket once already. I’ll try some pliers, or maybe make another socket. Thank you for the good info.There's probably a proprietary thin walled large socket that fits it (#^#@$@#). Like most people I don't have THAT tool, and don't want to find it.
I used a pair of needle nose vise-grips to get a bite on it. Regular pliers and vise grips can't fit in there. It just unscrews normally but can be tight if it's been in there awhile (likely). and not being able to get a good grip on it makes the problem more frustrating. Once you get the nut off the center part just pushes out. 2 O-rings. Simple clean, lube, and replace.
After a couple re-builds with THAT annoyance I took a cutting wheel and cut, then filed 2 large grooves in opposite sides of the 'nut' that the vise grips could get a solid, easy grip on You could also grind 2 flats down a LOT. There's more than enough metal on that nut.
My current 3D printer can do hard plastic down to 25 micron accuracy.and from what material would you print your 1mm walled socket
