HOW TO CUSTOMIZE LENGTH This PTFE Tube is sold in 4 different lengths. The 10 cm can be used to customize it. To set a custom length, multiple of 10 cm, choose the 10 cm variant and add to cart a specific quantity. E.g. if you need a tube with 50 cm (20 inches), select the diameter, select 10 cm length, set 5 units and add to cart. If you need more than one bowden tube with a specific custom length, define its features as indicated above, and click “ADD TO CART” once for each of how many you want to buy. All other available sizes – 40, 60 and 100 cm – are delivered cut to the selected length. Here is a quick guide on how to choose the right one: For 2.85 & 3.0 mm filament the 3.2/6.4 mm tube with larger wall thickness and smaller inside diameter will allow shorter retracts due to smaller hysteresis. The perfect choice for your Ultimaker and other bowden printers that use 2.85 mm filament. PTFE tube 4/6 mm (inside/outside) diameters, for 3.0 mm filament. PTFE tube 2/4 mm (inside/outside) diameters, for 1.75 mm filament.
