Hexagon hotend visualization
By thorn
Hexagon hotend from http://www.reprapdiscount.com modelled in OpenSCAD from physical measurements.I am not the original designer of the actual hardware hot end so internal construction and dimensions are approximated. Outer dimensions are as good as I can measure with calipers,Suggested use is as base for designing mounts, fan shrouds etc.
