After I had already designed multiple effectors that could be used for multiple purposes such as:

• 3D hotend.
• Laserhead.
• Pencil.
• small router.

I have now designed another effector that can be used for multiple purposes. I use it myself to easily change different Hotends complete heater and nozzle The hotend and nozzle coolers are integrated into the effector, so they can remain in place. The rods i doubled from 6 to 12 to eliminated as much tolerance on the ball joints. Also it's a more rigid system. for easier printing, i have split the printhead in two parts top and bottom.
