I frequently change between MMU use and special materials, or different spool sizes in single mode use (with larger spool holder on the side). With this splitter I just activate / deactivate the MMU3 in the printer menu, and can feed via the MMU3 or from the regular inlet on the side, without any hardware changes. Just make sure, to let the Nextruder behaviour set to MMU, if you modified it. Singe mode works with that setting as well.
Do not chamfer the end of the tubes at the intake side, but chamfer the tube of the outlet side. Just use a sharp drill bit, and rotate it by hand. Ensure to have perpendicular PTFE cuts.
Suggested print settings: 0,15mm Structural
