Too much entered for each craftsman (6)
I believe the answer is:
potter
'craftsman' is the definition.
(potter is a kind of craftsman)
'too much entered for each' is the wordplay.
'too much' becomes 'ott' (short for 'over the top' - informal British).
'entered' indicates putting letters inside.
'for each' becomes 'per' (I've seen this before).
'ott' placed within 'per' is 'POTTER'.
(Other definitions for potter that I've seen before include "Ceramicist" , "Maker of earthenware vessels" , "Producer of earthenware - move with little direction or energy" , "wizard > snooker player" , "Move unhurriedly" .)
