Cherry pitter with a spring mechanism - tuned

SKaranko has made nice cherry stone removal tool. Though, I noticed a bit room tune-up the design.

1) The rounded end, friendlier for you palm
2) Thump plate
3) Hammer head a bit longer and tilted more in
4) Position slots for the hammer & anvil

Added the original cup piece here as well.

Added CherryHammer with-out extra printing support
