Y-Splitter for 1.75mm

thingiverse

I'm impressed by this basic splitter, it works flawlessly! No complicated Bowden connectors are required; you can simply glue the Bowden tube directly into place. To assemble this device, start by cutting off the two top tubes so there's no gap between them. The bottom tube requires a flat end to secure it properly. You'll need two of these pieces and attach them together using M3 screws.
