I'm looking for a pulley kind gt2 idler pulley double head enough long (between 35mm and 40mm), the only one i see in the market is double head with length 27.5mm.
I have belt of 6mm, i need a bigger space between the 2 pulleys.
If i put 2 separate pulleys the motion will be separated because the axe should be fix (not moving). I would like the movement of one pulley to drive the other.
