Saw something similar but decided to have a go at making something slightly different myself.
the goal was a quick easy design, easy to print that would require no supports and no cleaning post printing.
This model prints without supports, the nose unscrews to gain access to the cash put in the jar.
The jar is obviously a pig but all my friends call it a Dalek! :-o How rude!
There are various noses, a plain one, 'Staff Tips', 'Xmas Tips', Plain and in Welsh, 'Coffi 50c', print whichever one you want!
