This splitter works perfectly and is exactly what I was looking for. I tried another model, but the filament would get hung-up in the splitter body, causing feeding issues/jams. Using a spare piece of filament to test the splitter, I could feel artifacts in the filament path, and the threading was not correct. However, this model was the exact opposite experience. The threading on this model is perfect and the inside of the splitter (along the filament path) is super smooth. I have zero feeding issues; it just works. Thank you!
