I Remixed the Y-Splitter to use the Bowden Collets leftover from my ERCF build.
I Printed this one on my Voron 2.4 (Still Waiting on the X-1) in KVP ABS with the single end on the build surface. I did use painted support on the interior of the single port only. I recommend 20% Gyroid infill and .2mm layer height.
The Collets fit tight and the splitter has an internal barb to secure the collets. Start them by hand then push them down on a flat surface. I had to smack them lightly to get them flush.
The author remixed this model.
