I add arcol.hu hotend support for Greg's Hinged Accessible Extruder. This is my first ever try with openscad. So the code maybe not the most optimal. Here it is the version 2 of extruder block with arcol hot-end support. I have widened the base in the middle, to not allow any movement for the arcol hot-end. Version 2 is untested! As I did not have the time to print it yet. The stl file is for arcol.hu hotend. The scad file can be set to any other supported head type.
