The E3D Hot End I needed a Solidworks model of the E3D-v5 to design my dual extruder mod. I did not model the fan shroud as I designed my own unique version for my setup. It should be noted the heat block represented is from V4, but should be very close to V5.3 and v5.5. If there is demand the model can be updated to include the latest heat block. This model was generated using dimensions provided here: http://e3d-online.com/Documentation I have included step, solidworks, and stl files. Please let me know if additionals need to be generated either here or on one of these sources: Download: Thingiverse: http://www.thingiverse.com/thing:236590 Grabcad: https://grabcad.com/library/e3d-extruder-1
