Remix of trash picker - with extended and round handle

I added a longer handle with a round ending on the excellent trash picker created by Andrew Lipovsky. 

I painted a bit of paint-on-support at the end of the handle gap (see g-code file for more details).

Hint, put some food oil at the PLA that goes into the channel in the front to make it work smoother
