SummaryThis is a clip on version of this this ( ). My machine runs way too hot on small layers so I made this to help without using tape to attach it to the front of the extruder. Good luck getting the support right, slic3r tries to add support to the little ducts. Cura getting it right with some setting changes but I can't get anything to print properly from Cura. I got it to slice right using Simply3d software and added the gcode file here for you to try. UPDATED I noticed there was an issue with the arms breaking off due to some extra surfaces in the model. Since this was my first attempt at 3d modeling I did not know how to correct it at the time. I've learned a lot in the past year and the interest in the part is still going strong so I went through the entire model and fixed all the issues I could find so now the model is a single solid that prints strong. It's not perfect so I added the Sketchup file for anyone that wants to tweak it. I'm leaving the original files on here as well so if you want the new version make sure you download the "fixed" files.
