Trash bag adapter Mark III

Recap - use smaller standard trash bags in a big trash cart for robotic trash collection trucks.

Mark I uses a wooden rectangular frame.  It was too clumsy to detach the trash bag from it after full.

Mark II uses inexpensive clips to attach the bag to the edge of the cart.  The clips aren't that secure.  The bag slags.  And tall bags are needed.

Now the new Mark III uses PVC pipes of course.  Crius clips are used to attach the bag to the frame. Any known issues are improved. 

Is it better than using a separate standard bin? Time will tell.
