Capricorn PTFE tubes are a must for any Bowden 3D Printer!
Capricorn XS Series Premium PTFE Teflon tubes are the best tubes you can get for any 3d printer. They have excellent tolerances to provide very little play inside the tube so you can reduce your retractions significantly. They are produced with a special blend of PTFE Teflon and is the slickest in the industry. This is the most cost effective upgrade everyone should do on a Bowden 3D Printer. Capricorn has also made another PTFE Teflon tube that is specifically made for heatbreaks as well if you use a heatbreak liner in your 3D printer.
