Stihl 015 Oil Pump Drive Sprocket 3/8 Chain

Stihl obsoleted this part which is needed to convert the 015 chainsaw into a 3/8 chain drive. The sprockets are available in numerous places but the oil drive sprocket is not. I measured the parts that this mates to, and printed my own on a Makerbot with a 60% fill. There isn't a lot of load on this if the oil pump is working correctly. If you have a 015 Stihl and you want to get a new sprocket for it, then you need to print out one of these.
