Phantom Plastic Printbody tighter with m8

made a easy to print version of the Body with tighter tolerances and an m8 insert instead of the screw in plastic version. just small but in my opinion good changes for this beatiful project.

It's a tight fit with 0.2mm tolerances so it won't wobble that much anymore and you can avoid using the spring. I changed also the round feets and make them with a false instead, so it's much easier to print.

Additional you can add a big  20mm washer under the self securing nut to spread the pressure better on the movable slab 

Easier to print, tighter tolerances, M8 insert
