This is a 2 into 1 filament splitter/joiner for 4mm OD x 2.5mm ID PTFE tube. 

The PTFE tube simply pushes into the bores. This is a tight fitting model so a poorly calibrated machine might struggle to get the accuracy required. The transitions are incredibly gentle, see sectional images, to ensure a smooth feed of filament without snagging.

A single M3 mounting hole is included if you want to fix it to something. 

Printed vertically with the two holes at the bottom, 0.12 layers in dried PLA, arachne walls. Outer brim only to help stabilise it. Make sure you slow the print down once youre about half way, so not to deform the cylindrical shape with too much heat. 

After printing use a fibrous (CF/GF) filament to "polish" the internal routings if you need to. Took me about 1hr to print on Qidi Q2.

.stp file and .stl attached.
