Extra poly-carbonate tubes are very convenient especially when you can refill the tubes all at the same time. These are CNC machined and will fit your 2.75 or 3.75 inch linear Ram Extruder for clay 3D printing. If you are purchasing extra tubes it is very important that you buy the correct size for your machine/extruder size. If you purchase the wrong size the tube, it will not fit on the ceramic 3D printer or the acme screw will not be able to extend to the bottom of the tube. If you do not know which size tube you have, you can check on the Printer Comparison Chart to see what sizes are standard on each of our models.
