Tube Cutter

This is a guide to cut PTFE Teflon Bowden Tube for MonoPrice Dual Extruder 3D Printer. It will cut 2.0mm ID x 4.0mm OD for 1.75mm filament to the correct length for the MonoPrice Dual Extruder. I was able to get 2 Meters of tubing for $6.00 on Amazon. It should work for the Flashforge also. You just trim the starting end of the tubing off square then slide it all the way into the guide and cut it off with a razor blade. To remove the tube there is a slot at the end to push the tube out. I was able to print it laying flat without support. This makes the cost of each tube about 10 cents.
