3D Printer Bowden Tube 2M, PTFE Tube Teflon Bowden Tubing with high Grade PC4-M6 & PC4-M10 Pneumatic Fittings,Tube Cutter, for 1.75mm Filament Ender 3/Ender 3 V2/Ender 3 Pro/CR 10 Series

If you 3D print you will sooner or later need tubing and fittings. Nothing special about these except they are quality, make a good spares kit, and include a cutter for squaring off tubing at a reasonable price. Recommend

Got exactly what was expected with fast shipment

With an Ender-3 I've discovered that when the prints go south and nothing wants to print correctly (with defaults and KNOWN GOOD gcode), start by replacing everything on your printer that comes in this package. I do the replacement while the hot end is at 200. I do it in this order; Raise Z axis 70 mm to whatever to gain height from the bed. Remove fan shroud and extrude 10 mm then retract by 30 mm. Remove filament. You may have a 'slug' at the end and it if it gets stuck. . .Cut filament or tube, doesn’t matter. Back off extruder nut and remove that end. Do the same with the hot end nut and remove entire piping. Remove HOT nozzle and run spare tube from the top all the way through heat block – don’t back it out. Replace nozzle that will QUICKLY heat up! Replace BOTH extruder nuts. Did you determine how much tube should go in the hot end once the nozzle was replaced? It needs to be butted on against the top of the nozzle and also squarely cut. Make sure that amount of tube is now pushed back into the hot end and lock the extruder nut with the clip. Do the same thing on the other end and you’re good to go. Just make sure the bed is level and do a test print on something small that YOU KNOW has printed successfully in the past. Good luck!One other thing. I’ve gotten other nozzles and specialty tubing, etc with limited results, quick failures, etc. This kit seems to be about as ‘original’ as it gets so I’m very happy (knowing it’ll go south again but at least this is the least painful solution I’ve found).

Teflon 3D filament tubing is considered the best.... Looking forward to using it.

It is a nice little Kit and I love the cutter it came with. Simple and effective. Good price and value.

Replaced original that broke

Perfect to thread on my printer and printed parts. I didn't know exactly what I needed for my 1.75mm filament connectors, and this covered me!

I purchased this kit for the Y-splitter I printed for my Bambu X1C. No issues with the components.

quality items in a neat little box . the cutter works perfectly even though it didnt look like it was up for the jobhappy with my purchase

Exactly what I needed

Do not buy this product. Metal connector broke in the feeder mechanism. Had to buy a new one.
