How to blend tube intersection
So i've recently got myself an Ender 3 and I though it'd be a good exercise to try and replace a connector used for a small marquee.
Here's what i've got so far https://cad.onshape.com/documents/b4a5f33f86870770968039da/w/090cf0dd1cb96a312af51725/e/5a48876a1a62859f23113984
I'm near ready to print off a sample and see how it compares to an original but I can't figure out how to blend the radii at the point where the four tubes meet. See image below for reference of what i'm trying to achieve.
