RE: Ok so how should I print this?
I would print with the two round legs sitting on the build plate.
RE: Ok so how should I print this?
If forgot to mention that looks weren't important for this project. Strictly functional.
So I forged ahead and I decided to print it standing on the 'corner' which seemed like it might give all three tubes their best chance to print without inner supports. Slicer added supports around the bottom to hold it up, but I used a blocker above where the tubes started because I didn't want to dig support trash out of the inside. Final result was surprisingly great! Just the way I planned it actually. I guess I didn't need as much help as I thought I might.
Thanks for the comment gkmakeit.

It is a good idea to look for Prusa Prints.
