Pitan Hotend EasySwap

I created this because I am changing Hotend regularly from PTFE to all metal and vice versa, but on original pitan you need to unscrew all screws to access hotend, so I replaced cover and bottom case with one that has easy removable hotend like NSTT extruder.

It consists of 3 parts; Lower case, upper case and hotend holder
I created all parts in Designspark Mechanical, but google sketchup files are added too.
