New bamboo skewers corner element

I am not sattisfied with the latest corner element for the steelrods.   I returned to the bamboo skewers and created a new corner element with 4 connections... In the following images you see how I constructed it.  It started with a cube.... and some math.

After I added a subdivision modifier and smooth the result I used  the boolean modifier to create the holes for the skewers. 

Here is the print after  39 minutes and  26% done.

Hera after 1:15 hours and 58% done.

And finally after 1:42  hours it is ready.  The infill is very good. 

A day later I printed another 3 pieces.  They took 5:10 hours to print.  The look good.

And here is a first assembly of the thing..
