Bowden Head Tube Guide Anet A8 Style

thingiverse

This device steers the tube of your bowden extruder so that it bends less or not at all when inserted into the push fitting on the extruder. I created this after the fitting on mine snapped and pushed the tube out instead of extruding, which ruined a ten-hour print. However, since I installed this device there have been no hints of an issue. It's simple to install between the screws on most Anet A8 heads. I've included the SolidWorks 2016 file it was made from, along with a screenshot showing how to set the distance. The distance was measured from the front of the bowden mount surface to the back of the tube, then 2.25mm were added to center the 4.5mm tube hole.
