The spools are half-empty, the colour is right, and the part is not finished. That is the moment a filament joiner stops being an accessory and starts being the difference between a completed job and a restart.\u003c\/p\u003e\n\u003cp\u003eThese PTFE splice tubes join two filament ends into a single continuous strand. The internal bore is sized for 1.75 mm filament, the wall is thick enough to guide the material into the hotend without kinking, and the cut ends sit flush inside the tube so the transition passes the extruder gear without catching. Each tube measures 37 mm in length with a 1.8 mm inner diameter and a 2.6 mm outer diameter.\u003c\/p\u003e\n\u003cp\u003ePTFE is the right material here because it is slick and heat tolerant. Filament slides through with minimal friction, and the tube does not soften or deform in the short distance between the spool and the extruder. The result is a splice that behaves like continuous filament rather than a repair.\u003c\/p\u003e\n\u003cp\u003eWorkshops that run long print queues keep a stock of these on the shelf next to the nozzles.
