Hello peoplez.

Re-designing Y axis motor to shaft belted transmission for gt2 belts.
I need to accomodate existing shaft placement and need 40T pulley dimensions.
8mm shaft centre is ~30mm off the deck.
Looking for GT2 pulleys on ebay and no one lists external dimensions for the pulleys they sell.
Anyone got one to give me outermost diameter ? Flanges and all.

At the moment trying to do nema23 motor 20T(6.35mm shaft) to 40T(8mm Y drive shaft) 10mm GT2 loop belt transmission in place of inline nema17.

Dont have much space to play with...
