Strong Pulley for M3 metric bolts w/ bearing

thingiverse

I liked the pulley for econopotamus but wanted to use the bearing I had laying around. The side and hanger blocks are the same, but the wheel is replaced by two parts which fit in/around a default bearing. When printing of the outer part is about to finish, I found that inserting the bearing into the still hot part helps to fit it in perfectly. Once the part cools down it will shrink a bit and hold to the bearing.
