About this 3D model

Lightweight 2-piece Cover for Ultimaker Hotend (V2). I printed out the nice cover by Thingster that was based on the design from Gijs. I agree with Thingster - it really improves the look the Ultimaker extruder. I decided to tweak the design a bit. First, I lightened it up by about 40% and created an interlocking corner section. Check out the updated version does not touch the wires: http://www.thingiverse.com/thing:115488 UPDATE 9/17/13: Per request, I have created a cover for a dual extruder print head (PrintheadCover2X.stl). I have not tested out this design, so let me know if it does not work for some reason. It was a pretty quick hack - I just cut it in half and mirrored it. UPDATE 6/13/14: Per request, I have included the source Autodesk Inventor CAD files.
