Got it printed over the last 2 days. Was in a bit of a hurry so I ran the machine really fast so the print quality isn't quite up to par.
It works!... Kind of...
I made a small mistake in the hole alignment for the side port so flow was partially blocked.
It was a 2 minute fix in the CAD so I'll make another tomorrow.
No leaks even though I didn't use any gasket material. I used a .3mm tolerance between the top core and the body. It came out about a half mm too tight. I used a hand file to take it down a little and it fit perfect.
I was concerned about leaking from the shaft thru the bearing, that fear was unfounded.
After that I made a radiator to go with it. It's a little overkill for the machine but it was fun to make.
