Toilet Flush Button (TALLER)

Ok, a bit of a cop-out on the "Upload a design per day" new years resolution.

07/01/2015 - damn- been date stamping "2014" on previous parts.....

This is a button with a longer axial length. What was wrong with the last flush button I uploaded? -It went Sub-flush(!) and required pressing below the surface of the cowelling. I think it's more hygenic to have a button you can depress fully with a palm, fist or similar.

Shorter length button (original):
