The Light  Green Jaws are curvy and narrow in towards the bottom.  These could work well in mugs that have a greater volume at the top and narrow in towards the foot.  Example: pint glass
The diameter at the top of your mug can be no smaller than 60 mm (2  3/8 in) or the widest section of these jaws will be too big. 
Smallest the foot of the jaws (part that will go near the foot of your mug  is 26 mm (1  in)
Smallest the top of the jaws (part that will go near rim of your mug  is 52 mm (2  1/16  in)
Jaws are covered in 1/8 foam
Redesigned jaws to improve stability and it no longer matters which order jaws are inserted. Previously jaw pieces were labeled M, U, and G and they were inserted in that order.
The new jaw sets range in price depending on how long they take to print, how much material they use, how much work it takes to apply foam etc.  
The light green 003 set is 45 Canadian, which is around 34 USD depending on the exchange rate.
