Rowan belt mod gear extractor and pulley spacer

thingiverse

So, you are like me and got stuck at removing the old gear from the stepper's axis and did not have a small gear extractor lying around ? Do not despair! Here's a gear extractor for exactly that purpose. Well, it's made from plastic, so it won't last forever but it is definitely good for removing the two gears you need to get out when you do the belt mod. And I have added a spacer of 5.5 mm which is the distance you have to lift the new pulley above the steppers' groundplate as it is pretty hard to measure with a caliper.
