101hero printhead swappable door

101hero printhead door improvement. no longer required to remove screws to swap filament

The parts should be oriented in the slicer so on the main body the large flat side is down with support under the pins. the small part should have the flat side with the finger clip down. will reupload STL files once I figure out how to orient them properly.

v2 parts added. thickened parts for more regidity, added screw holders to allow top clamp part to stay on screws at all times. reorient both parts
